Alright, so I've got the same issue as before with the launcher. When I start it up, it installs something, then downloads the same patch, then the START button lights up. However, it won't start up now since another patch has apparently been released since the last time. Can anyone else offer me some advice?

Hmm, Is it fully patched? (1.51.54) If not and it keeps downloading the same patch i'd suggest manually patching it
