Ok, so I installed Retribution, patched it and it works. BUT, if I try to join any server, all I get is the message that I can't join the game and that my files may be corrupt. It suggests reinstalling the game, but I have limited bandwidth and cannot download it again (not to mention the patching). Any help would be much appreciated.

Bump, This is happening to myself and a friend. We just want to play the game

There should be an option on the patcher screen that says, "Force Verify." It's under options.

Click that, see if it works after it's done.

Force Verify didn't work, I've reinstalled a total of 3 times, 2 times off of steam, and once off of the official site. It also gives me a video driver warning at login screen. Telling me my drivers haven't been updated in 27 months, i've check for updates and there are none. :|

Do you have everything updated though? Punkbuster even?

I've reinstalled PB, added the game to it, and updated, will try again.

EDIT: ~Still no change :|

If this helps: Im able to run the Tutorial, and play through all of it. Just nothing online.

FIXED IT!

1. Go into your programs and uninstall nvidia physx
2. load up the game, and go to settings > video > then disable Direct X 11 and restart the game

This worked for me too. Cheers mate.
