Installed again clean after uninstalling and "A referral was returned from the server" prevented me launching, again.
I am very casual with computers don't use them for anything else than gaming, emails etc so i cannot find a-work-around this. One thing that propably doesn't mean anything, is that when i got an installation that did work, the installation allways made Mumblelogo shortcut to my desktop. These referral-installations never do...
All in all. With out any rage/doom/qq intended, i think i need to end my sub with mumble since the product doesn't work for me. Hopefully a solution comes up at some point, till then i need to look elsewhere.
