So I bought BF:BC2 on Steam yesterday as it was on sale, and I'd been waiting for such sale for a while.

I don't know about the PC servers, but the 360 servers were very sporadic for a while a couple months back.  I remember I had to do something to get it working again properly.  Did you download the Vietnam expansion?  I think I had to delete that from my HDD and reinstall it.  Maybe just try reinstalling the game overall.  Sorry I can't be of more help.

I had this exact same problem... I can't really remember what I did to fix it...

Update your punkbuster directly from the pb website.

Does the Steam version have bfbc2updater.exe? If so, run that.

Alright, try opening these ports:

 There are no EA servers, leave that box blank

And also doing what Infininja suggested.  "

Be sure to update PunkBuster or you get booted out of games left and right. It kinda sucks.

this should solve you problem

Are you pressing the search button, the list will be blank until you actually search.   Otherwise i'm stumped because i was playing yesterday with no problems.

Of course I pressed fucking Search. Although it is still being a mardy bastard and now claims it can't connect to the main EA server or whatever. WILL PERSIST.

Anyway, when I bring up the server list it claims there are no servers. I can log in fine, which is what most Google results claimed the issue was. I can view leaderboards too.

It is allowed through my Firewall. The game, and Punkbuster, are both updated.

I'm running through a wireless card to my BT homehub, no idea if that is the cause?

I'm also running W7 Ultimate 64bit.

Anybody have any fixes for this? I wanna play me some multiplayer darn it.

Thanks.

I'm using the latest version of Kaspersky and have no problems, hence I didn't check the list. Forums are down, so I can't link the FAQ thread. I think it's a sticky there. Those dudes can definitely point you in the right direction. Just make a thread or search the forum. It's in there somewhere in great detail.
