Suddenly Corrupt File

I was in a game with a friend the other day and all of a sudden I lost connection to EA's server. I quit out and then my PS3 froze, so I turned it off and then back on. When I went to get back on I noticed one of my three save files(standard, classic, and hardcore) now said Pure Survival. Guess which file was corrupted.....My freaking standard save in which I have over 114hrs of game play glory on. I can access the file and all my stats, weapons, suits, etc are all there, but I can't join any of my friends games because I am not in the right game mode. I can only play in Pure Survival mode on this formerly Standard mode save. I am so pissed off it is not even funny. Worst off all I eventually accepted this fact and went to start a new standard mode file and in this new save I can't access my maraurder pack, tundra recon or my freaking devil horns!!!!!!!!!!!!!!!!!!!!!!!!!! For the love of God....HELP MEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
