As the title says, that is the error that it gives me whenever I try to join one of my friends games. And when they try to join me it says "xxx player has incompatible version". But all of us can join some random room and all be in it, but we cannot join eachothers game.
Now here are some facts about this whole thing:
1) We all have downloaded the same file from the thread "Download BK-MOD", we have all installed the exact same versions (126.96.36.199 > 188.8.131.52 > 184.108.40.206 > 220.127.116.11 > 18.104.22.168 and also the map pack 4.0)
2) We all ran the game via Blitzkrieg-Mod.exe directly
3) We tried to join eachother with and without Relic DLer on, both times we got the error
4) We can not see eachother's game in the lobby, however we can see other people's games (NEW)
We also tried to play Blitzkrieg with the new steam version, and when we tried to join eachother via an ingame invite it would give the same error as above but when we tried to join eachother via steam invite (manually: right-click, invite to game) it would do nothing.
I don't know what to do here, I hope someone can please help me out because it's getting really annoying that I can't play a game for a false reason (incompatible my ass).
