I have taken about a year long break from Ragnarok and I'm trying to come back. I am currently not able to. I downloaded the full installer and when I click start it acts like it's going to open and then quickly closes. Also I don't know if it's relevant but when I go to setup there is no screen resolution options. It's just a blank screen. I would really appreciate a response cause I've been dying to play RO again! lol
