I recently encountered a GameGuard problem with another MMO called SevenCore online.
It gave me GameGuard error 114 (means GameGuard failed to start or clashed with other programs)
Immediately, I searched Google for solutions. You can try some of these like:
 Allow GameGuard from Trickster Online to bypass your pc's firewall
 Turn off firewall completely
 Delete the GameGuard files in the folder, then patch again
 If 1 and 2 don't work, maybe exempt GameGuard from your AntiVirus software
 End programs that may potentially clash with GameGuard
 Now my computer had this problem: something screwed up in my pc, so I formatted my drive and reinstall OS. Got the game to run successfully afterwards
Not sure if these will work....
Good luck though
