Dumb intel infinity ward problem!!

I've posted about this before, but I just took the next step and I am really irritated.

So I'm sure everyone knows about the COD4 intel problem. You turn on a cheat and you collect the last intel. You are screwed!!!

I tried deleting the save, using a different disc, everything!!
My last resort was to click new game. I did. I still have all the damn intel!

How the hell can I get my last achievement!! I can't stay at 980 forever, that's just embarrassing

Clear your cache... try again.

BTW, staying in 980 beeing embarassing, Wow :o
