I remember helpping a couple of people over msn with a very similar problem...
As in the other posts raze mentioned
Battlefield Noob Most of the problem was caused with spyware loading at startup.
In that link is a link to a program called spybot. Please download it and run it.... there may be something hiding on your computer (that doesnt affect other programs visibly, but that prevents the game to access all the nescesary files it needs to run) that is causing this...
Also try the housecall (even if you have a antivirus installed, its very common for antivirus packages to not find and stop everything).
If these two dont stop the problem, then try the end-it-all program.
