Ive managed to rescue a career the other day by simply copying the main.cfg file from a backup career into your career found in my documents. Ive had similar problems and did some poking around. The main.cfg file was changed and on opening it it read 000000000 for a single line. It should have your game settings etc in it but they had gone. Repaired the career by copying the one found in the backup folder. This might help you too.
