Crashing to desktop

[Parmetheus]

I've been playing P99 for a few months now and since the beginning I've been dealing with crashes to desktop. The error occours sometimes 5 times in an hour, other times i can play for 4 or 5 hours with no crash. The message i recieve says:

"The instruction at 02309430x02343 (Not exact numbers..dont think it matters) could not be written, the program will now close"

or something along those lines. I've ran memory diagnositics, harddrive checks, uninstalled and reinstalled to a different phsycial and logical harddrive. I've swapped my Ram sticks.. I'm out of ideas. I'm running a Geforce 560 on Windows 7 Ultimate 64bit.

Recently I've made it worse.. I uninstalled and reinstalled to a different harddrive, and now I'm still getting the inconsistant crashes, but now it wont save my UI... Every time i close and reopen the game it "forgets" my keybindings/chat windows/hot key setup. Please help!! 1kpp to anyone that tells me how to fix these issues...seriously!
