Can't Join b/c host has DLC you do not.

I wasn't aware this game had any DLC at this point, and this happens to every server I tried connecting to. Didn't happen yesterday, started happening after patch earlier today. Or is my game corrupted or something?

I think it's the server that hasn't updated and you have.

I believe so too. Just check the name and see if it says "patched", if so, that means you can play on it.

Bad thing is, I see maybe 16 servers and only 4-5 have good pings, so that means only 1-2 servers have the patch added. :cry:

This message indicates that you are updated and the server is not, or vice versa. I'll make a note that a more descriptive/accurate message would be useful.
