I just installed version 2.0. After launching I get a Language Selection screen where I can choose English or Korean but I cannot get past this point. Nothing seems to work except killing the app. =( All versions through 1.95 work fine for me...
I don't see a "next" button anywhere. Don't know if it matters but I am running on a 3840x1080 display.
Additionally - I just tested lowering my resolution to 1920x1080 and I can see the other buttons now. I would prefer to be able to run at native resolution though.
