Connection Failed problems

[HAND OF GOD.]

No matter what server I attempt to join Red Orchestra gives me a box that says:

Connection Failed
Connection Failed

twice like that, and some servers give me the connecting screen for a couple minutes and then gives me the Connection Failed box. I tried opening the ports, and even shut down my anti-virus software and firewall but that didn't help. Put myself on my router's DMZ. Tried deleting the clientregistry.blob which also didn't help. I also tried copying my steam.dll from the Steam folder to the common/redorchestra/system folder. I validated my files twice and that also did nothing.

Practice/singleplayer works fine

No clue what else to try. Thanks to anyone who can help.

Try going to

Steam
File
ChangeUsers

And log out using that method then logging back in.

If you still can't seem to connect to a server something might be up on your end because the backend looks fine here as far as I can tell.

Nope, that didn't work either, could you point me in the right direction? I would really like to try the multiplayer.

Make sure all the ports RO needs are open on your firewall/router. You can find the list in the server support forums.
