I downloaded it today and tried to install it in a separate copied directory. I have a legitimate copy that I use, however, even with the environment set to medium the game crashes (1, 1on1, 5on5). I'm going to try to do a fresh install with no mods installed. The directories that I use now have quite a bit of mods installed, though, usually just art files.
I thought it might be something in the feconfig since I edited that and hwconfig to play at custom resolutions (when changing to a custom resolution in hwconfig, you have to edit graphic settings through feconfig since in-game it will crash if you save it).

Edit: Fresh install completed, I have also made a backup of the original install on my external HDD. So I will proceed with the 6 part install.
Edit2: After some tedious tweaking, I have learned that with this fresh install I cannot 1, 1on1, or even 5on5 with my resolution at 2048x1024 anymore. I had to change it to 1024x768 for it to work, also, the loading time for the non-modified executable is horrendously long for some reason. My disc is rather worn but... takes about an entire minute or 2 for some screens to finish (first world problems lol) sometimes. I haven't tried the No-CD with it yet, as I've read somewhere that Rucker park would definitely crash. The time difference I think may be because of the disc itself, increased loading times anyway.
I was able to successfully enter a game and practice mode finally, however, look at this-
I'm assuming the above image has something missing, this was the Nets x Hornets.
Nevermind, I found out why, environment setting wasn't set to medium. Now that it is I'm able to play, though the loading screens take longer. I also cannot use 2048x1024 with the Street mod.
