Leftos, this is all of the information I have gathered so far on my issue of the game crashing whenever it connects to 2k's servers.
I will be reinstalling Steam tonight onto a different drive and redownloading all of my games to see if that fixes the issue.
UPDATE: After reinstalling the game with no success, I tried completely removing Steam and all of my Steam games and doing a fresh Steam install. This was pretty much my last try before talking myself into reinstalling Windows over this. (This Win7 64 installation is like 3 months fresh so I was not looking forward to that idea.)
I Installed Steam onto my D:\ (programs) hard drive instead of my C:\ (OS SSD) this time and also installed NBA2k15 to D:\ and then went to sleep. I woke up and everything was downloaded and ready so I launched and I'm happy to say FOR NOW AT LEAST the game is working flawlessly on my system.
I hope this information I've gathered helps track down what causes this problem, but for me it seems the problem is fixed and I can finally get down to playing the game online.System configuration

Update: I just downloaded and tested the game on a different machine at my house. It has a similar CPU (Phenom X4 945) and a Radeon HD5770 and it is also on an Asus motherboard. I am using the HDMI Audio from the GPU just like on my machine above. The game launches and goes online PERFECTLY on this machine however. The two systems are so similar that it just baffles me how one could work with the game online and one cannot.
This proves the following
1.) The problem isn't location based. I am able to connect and play nba2k15 on the other computer from the same house on the same router.
2.) The problem IS with certain machine configurations having some kind of incompatibility with the game connecting online.
I tried downclocking my CPU to 2.8GhZ and the game still shuts down when connected to the internet.
I tried putting this machine on the 14.4 Catalyst drivers and the game still shuts down when connected to the internet.
I tried putting the latest drivers on the other machine (needed update anyway) 14.11.2 Beta. Game still works. Crashed once in My Team but I think that's because I opened the Steam Overlay during a cutscene.
Old InformationI launch the game in ONLINE mode and it gets to the splash screen or sometimes to the NBA teams screen and it just closes to desktop.
So I did a little bit of troubleshooting. Since the game launches fine in Steam OFFLINE mode I know I'm not having any kind of video/configuration related issues, so I threw that idea right out the window. I then restarted Steam in ONLINE mode and then disabled my network adapter. I launched the game and it made it all the way to the main menu and said it couldn't connect to 2kServers. With the game still running I enabled my network adapter again and hit the connect button, still couldn't connect to anything. I tried a few more times and it eventually closed my game to desktop.
I've been watching some Youtube videos and I found a guy on PS4 who gets to the main menu and cannot connect and then has a friend of his invite him to MyTeam which forces him to connect to the server and then he can back out and do whatever he wants with the game working correctly online.
I am currently waiting for one of my friends on Steam to come online so I can test this last part, since I am now able to successfully get to the main menu with Steam in ONLINE mode by disabling and then re-enabling my network adapter.
I will post the results of the PS4 friend invite trick ASAP.
:UPDATE #1: I disabled my Intel CT PCI-E Network Adapter, and enabled my motherboard's onboard Atheros L1E Ethernet in order to test if it was something with my network adapters configuration that was causing the game to close. The game behaves the same on my onboard as it does with my add-in card. For the hell of it, I installed another PCI-E Network Adapter that I had lying around, a TP-Link one. Same results.
:UPDATE #2: So my friend hasn't come online yet and I'm still waiting on that, but I have found 2K's server IP and found that I do establish a successful connection to their server and then my game crashes. So I am 100% convinced that something is occurring with the handshake process that is causing the game client to just shut down. If the game cannot connect online (network card disabled, ethernet cord unplugged, peerblock blocking the game server) it will fail to connect and the game will remain running. The second you allow it to talk to the 2k servers the game closes.
:UPDATE #3: My friend came online and I had him invite me to a MyTeam game. I unblocked my game client which was sitting at the main menu and took his invite. The first attempt said that a Connection could not be made to the servers. The second attempt was a successful connection and my game client immediately closed.
I am now convinced that the crash is happening when the game connects to 2k servers.
