I had the same issues when I went to two rigs, and I think it has something to do with the fact it's not connecting to the second PC. On your first copy, in the title bar, is the address. In the second copy, go to the settings menu and I think it's under commands (I'm at work, but this should be close) enter the (correct) address of the first copy, and check "Auto-connect". If you've done this before and it worked before, make sure the addresses are the same. When I had a cable modem replaced, my addresses changed, so that could be the issue.
