SpecWarrior 0 Posted June 5, 2009 I'm just back into arma after some time. When trying to join MP server I get a message saying "uses modified data file - CA" What does this mean and how do I fix it? Share this post Link to post Share on other sites
no use for a name 0 Posted June 6, 2009 it means that your CA.pbo doesn't match the one on the server because a) you're not using the same game version as the server. b) an addon that you're using has either modified it or loads a different one c) it's corrupted for whatever reason and you need to reinstall First thing is if you're running addons, disable them for multiplayer because most servers run stock ArmA unless specified If you don't have any addons or it still happens, then make sure you're running the same version of the game as the server. When you go to the server page in the game, in the lower right it says what version the server is running Also, some servers require addons so make sure you have all the right files before joining Share this post Link to post Share on other sites
