Just to let you guys know, for the lack of any support to this game, i opened a ticket with steam (before release) and got my money back!
They only do this if you opened a ticket BEFORE the release of a pre ordered game.
btw. UAC is the very first thing i deactivate after every Windows installation on my PC. I tried every compatibility mode the only thing that helped was a damn CRACK.
Everything is deleted now, i'm out,
cya at Star Trek Online!
