It also happened to me 3 times, in these last days:
- while logging in: it gives me that error, or the screen remains in "Welcome to PR" i can move the cursor but cant do anything, i can't even alt+tab to desktop and kill the bf2 process...
- during a normal game: after some (voip)lag i just get LOGGED OFF pr, with "error reading from server"
The next time i try to login it works perfectly, but its still annoying
