There's 3 Types of GameGuard Errors. First one is : GameGuard files are corrupted, which happens when you try to bypass GameGuard. All you gotta do, in that case, is to uninstall AVA and re-install it, it should take about 30-30 minutes depending on your PC Perfomances. Second one is : GameGuard .erl files Errors. All you gotta do is go to : c:/AeriaGames/AVA/Binaries/GameGuard and delete all the files in there. Then just load the game and GameGuard should automatically re-install correctly the files. Third one is : "Either GameGuard or the game is already running" All you have to do is delete the files there : c:/AeriaGames/AVA/Binaries/GameGuard and load AVA. GameGuard should automatically re-install the files correctly. If it doesn't work, uninstall AVA and re-install it. As i said, it should take no more than 30-40 minutes.
