Well, I suggest that you examen the computer first and find the reason for that crash. After that you may try to make account again and maybe the problem will be solved. If you still have problem, try to contact support group on developers and publisher sites or by phone. If you call by phone. If you try it over the phone first listen to the automated message on the other side, and press the button that you should press. They will fix your problem with avatar and logging in no time!
