GameGuard Issues
If you're having issues with GameGuard and you run Windows 7, take a look at this thread:

This was for The Chronicles of Spellborn but applies elsewhere as GameGuard is a global client and not tied to any specific title. It will at least get your GameGuard version updated to a version where it can patch itself with Aion's libraries.
If you are still having no luck with GameGuard in general, take a look at this thread as it lists many background applications that can interfere and trigger GameGuard to close your game down:
