Crash to Desktop when connecting to a server

[killaer]

For some reason every time I try to connect to a server I crash to desktop. Why? How do I fix this?
Recently, Every time I select a server to connect instead of putting me to a connect to server screen I just get booted right out of the game to the desktop.

I have:

nVidia 7950GT
2gigs RAM
Pretty good dual core AMD processor

I've got the latest nVidia beta drivers.

How the hell do I stop this from happening

Problem - Crash to Desktop on Joining a online Server
Cause - No CDKEY in Registry
Fix - Use battlefield2_code.exe to re-enter your CDKEY, this can be located in the support folder of where you installed battlefield 2 on your Hard-Drive.
After re-entering your CDKEY you must then reapply the latest patch in order for it to be encrypted into the registry.
This Program can also be used. (Note - This Program appears to do nothing visually, but it did change the registry key)
