ATG spartans problem-not compatible data game on multiplayer

[Spartan_Heroism]

Hello,
I had 1 of the spartans installed. Realised i couldn't play Multiplayer anymore so i uninstalled it and changed everything in data as it was b4.The old spartan model and unit card came back , but still when i was going multiplayer it was saying at all the hosted games that "Not compatible game data".
What do you recommend me to do to be able to play multiplayer?

Thanks a lot

If you want to play MP always make sure you have a clean copy of R:TW and use that. Something is different between your install and a vanilla (clean) install.

If you want to play a mod then simply take a copy of the 'clean' install of R:TW and install the mod to that. I personally have taken a copy of R:TW for each mod that I play and even for each version of the mod - that way I know I will always have a working copy of the game.
