I'm unable to join or create games.

Creating or joining a game gives the same error. I'm running a fresh install and I'm on patch 1.13c with the latest Ultimative patch. Any ideas?

This error usually occurs when you have the wrong median version.

Redownload from here: http://www.moddb.com/mods/median-xl-ultimative/downloads/median-xl-ultimative-xvc and let us know

Edit: also make sure you are not on 1.13d by accident. This can be the case if you connected to regular d2 battle net with your installation.

Alright, that's the version I have, but what I did was overwrite the patch_d2 with what I had and it works now. I did originally have to downgrade to 1.13c and I think that may have screwed things up. Works now though. Hope that helps anyone else who experiences something similar.
