Thanks guys I hope I can play now

Whoops my bad then, hope you get it working. I'll save this for future reference... sometimes I go to Canada, was afraid I wouldn't be able to play if I traveled, 'cuz I don't wanna use VPN all the time. Still weird why the region restriction exists though.

there should be a cookie hack for the game like on most DMM's games
