When I log in to the game, after 2 seconds a windows shows. It said that hack was detected. I felt kinda weird, because I didn't use any hacks, tried to play for first time, so I switched Norton, used Registry Mechanic, but after these things, a new window started to pop. It says to delete the GameGuard folder. I'm doing it all the time, and all the time it says the same. Anyone sloved this problem? Help, please. Tried to reinstall the game twice.

i had a problem with it kicking me and said to delete game guard folder and then when i reopened the launcher to play it gave me an error after reinstalling gameguard.. i just closed, ran launcher as admin, manually repatched and re ran the game..it installed game guard again and error was gone..only problem was i had to forfeit my quest and re accept it because it happened when i went to do my master class quest and kicked me out of the DEF TEST center

Thanks for reply, but it doesn't help me much. I'm being kicked right after I log in.

EDIT:
Got it. I uninstalled PunkBuster, it was other Anty-Hack tool, installed by other game. Now everything works fine. Close/Delete this thread, please.

@v
Try to uninstall not-used programs from your computer, or any other Anti-Hack systems such as PunkBuster, or AhnLab one. Worked for me, worth trying.

vidoceq dont ask to close/delete this thread you insane what if other peaple get same problem and search for help on fourm when you both found awsners. i have the problem as well

Sorry for bringing back a week old thread, but I'm having the same problems at the moment.
I've done everything to get in, reinstalling, manually patching, taking out the english patch, opened the firewall for DBO.exe, deleted the gameguard folder, and running everything under administrator.
But I'm still getting this GameGuard pop up everytime I get in game after the loading screen.
Any suggestions ?

As I said, try to uninstall any other anti-hack tools. Like PunkBuster, or AhnLab Hack Shield.
