I've only used them for Perfect Worlds Neverwinter b/c I have no choice.
I was actually told that if it's not working, then that is the way it's suppose to work (paraphrasing), but no kidding.
They have Zero knowledge of the game so if you have a problem with the actual game, don't bother.
It's incomprehensible to me how EVERYONE is so displease (in the community) with the level of support from Arc Games they they are still in business, but I think that I know why.*
* I see the reviews below give 5 stars to Perfect World or the actual games.
Do not be confused, Cryptic Studios designed them, Perfect World developed them, Arc games supports them (from the little info I could find).
All Chinese companies.
