Pr CTD when loading

Posted this on the PR forums, but i'd thought i post it here just to get more help.

Alright i'm having alot of trouble playing PR A.T.M, a couple days back i start PR and attemted to join a server but came up with the error "Your CD-Key is invalid", so closed PR and went to Code:

C:\Program Files\EA GAMES\Battlefield 2\Support\Battlefield 2_code.exe

to renter my cd-key after this attempted to start but Pr only to find when i did the splah screen came up and disappered as it usally does but after that there was nothing, but BF2.exe and PR.exe were still running. Confused by this i tryed a reinstall which fixed that problem but now when ever i join a server the game CTD when it is "Verifying client data" i tryed a few things to fix this problem such as updateing my drivers and changing the video setting but still no luck. A friend (stupid Wolf giving me bad advice) said this might have been caused by running the 1.41 patch can installing Pr in the wrong order so i went to reinstall the game again being carefull to make sure that they are still in the order but still the same problems.

Now i am out of ideas to what could be causeing this, the only thing i can think of would be that something in the registry could be causing but but im doubtful to this, So can anybody help me fix this problem besides a reformat which is not something that i want to do.
