Corrupted file

My computer crashed, while i was playing association and now when i try to load it back it says the file is corrupted. Any way of fixing this?

Try opening it in REditor and saving it again. Otherwise, unless you've kept a backup, I guess you're screwed.

I'm having the same problem with my Assoc mode. I'm on my 3rd season and the game runs fine until yesterday.
The game and my PC crashes while in the middle of the game. I also experienced frequent freezing (for about 2-3 seconds) while playing the game and even in the menus. I am not using max settings since my PC can't handle that, but there hasn't been this kind of problem ever since.
I tried re-installing the game and using the lowest settings, still no good. I wonder what the problem is, hope you guys can help out.

If the Association save is corrupted, reinstalling the game won't do anything. All you can do in that situation is start over, unfortunately.
