It seems the guys over at evenbalance did a boo boo and are releasing pb updates left and right at the moment.
For now its recommended to dl pbsetup.exe here
http://www.evenbalance.com/index.php?page=pbsetup.php and use it to manually update bc2 update.
Our servers will need restarting now as well so the server pb files will update as its not doing it automaticly for most people/servers at the moment. will happen when someone wakes up.
UPDATE: pbupdate seems to fix it now
just dl it. run the exe. select bad company 2 off the list of games. make sure u clicked it once more after selecting it and click update
