I can't launch the game without using a VPN. Every other game works except Rumble Fighter. Only thing I can think of is my college internet???
After updating your game client, you should no longer need a VPN. You can also turn on the VPN while the patcher is up - then turn it off after the patched is finished. If you are still receiving this error, this could be caused by the internet firewall that is in place at your college. Please contact your internet technician or administrator to see if that is the case.
