I tried adding key on new computer - it started to sync correctly for me. So the issue is something on your side. Maybe router configuration or something?
Thanks for your answers.
I appreciate the search link; is that actually anywhere on the forums as well? Can't seem to find it...
The Bittorrent key works fine as well; I installed GetSync on a new computer and it didn't seem to work; once I actually finished setting up GetSync and created an account for the new machine the key worked fine.
