[Wrong client]

Same happens to me 

[Concrete Matchmaker is Null]

Got this error when i was waiting for some one to join me in the crusade map. 

The game seemed to add me to a group with to other people (one more then the map allowed) and when i pressed the globe the game froze, and gave me this massage.  

Windows 7

[Update: Logo Removal]
