Thanks for your post!
Sorry you are having trouble making connections. What region are you located in?
With some additional information we can assist further.
All the best,
I am having the same problem. Please help! Im in the midwest. The other two computers in my office are connecting just fine without being asked for the partner's number.
So the computer show as online in your Computers and Contacts list? Does the Server show up on it? Have you tried disabling any firewalls on the server (as a diagnostic step)? Does the Server have internet access?
