Hey man, i was the guy who said yesterday that the game is crashing everytime I try to go to a next game, read headlines or go to a team schedule with the player i chose, and it was Dwyane Wade btw. This is how i made this work:
I did everything the way you said, but I have chosen one of the real rookies, it was Jordan Crawford from the Wizards. I've tried to go to schedule, next game and things like that and game DIDN'T crash for the first time. Then i saved the game, quit My Player mode, minimize the game by pressing ALT + TAB, and then i have chosen one of the veterans from the list. It worked for me.
The only thing that you have to fix is a existing rotation. For example, whatever player you chose, you are going to start with 0 minutes. I've only played 1 minute in my first game as Wade... It would be cool if you can fix this, so that i don't have to play 10-15 games averaging low or average numbers just to get my minutes around 40, which would be realistic for a guy like Wade.
Btw, nice job on this, it's a cool thing, i just hope that the first update will fix those small mistakes you made.
