Having troubles with revision control, Need desperate help ASAP

Not sure what causes it, but i cant connect to revision control for multi-user at all, im using hamachi as a server host, my friends and i dont have the money to pay to work together and get stuff working.

I cant “select” anything other than Multi-User, (i can, but it stays as multi-user, and wont “change”,)

And i get this in the log for Revision control.

This i a major issue as its stopping me from continuing development with my team, cant find a fix for it anywhere and dont even know what the hell caused it. PLEASE offer out a hand of support on this issue.

I’ve reinstalled unreal, repaired the previous installing, clean wiped it, installed it on a separate drive, nothing is seeming to solve my issue. Someone had suggested that my firewall was breaking it, but it looks like it has access. I no longer know what to do and im just considering going back to unity for development.
