GlennD I'm having the same issue/ errors as described earlier in this thread.
I can connect to other workstations on my domain remotely so I used RDP to access my workstation and then uninstalled all LogMeIn software and reinstalled via download links from GoTo Central. I did the same with the computer I am connecting from.
Initial setup of LogMeIn Control Panel was having a few issues - First it was unable to start the LogMeIn service. I was unable to manually start the service via services.msc. The LogMeIn Control Panel had a pop up stating "Enabling..." with a spinning circle and I had to force close the Control Panel. After another restart The service was started, LogMeIn Control Panel showed "Enabled" but was not Accessible due to the workstation not being connected to the internet (as I was remoted in from 20 miles away?). Connection/Event Monitor was saying LogMeIn believed the workstation only had a loopback.
I closed the Control Panel, force closed any processes related LogMeIn, manually stopped any services, and flushed DNS. Ran LogMeIn again and no change. Restarted, remoted back in to other workstation, rdp'd back to my workstation, and the issue was now resolved. LogMeIn Control panel showed Enabled and Accessible. I signed out of the RDP session, signed out of the LogMeIn session to the other workstation, and tried to log in to my workstation via LogMeIn Client. First attempt states the connection was lost (Hangs on the Verifying step. I have checked that the cert used for my workstation is the same one used for the workstation I can log in to. Both workstations are on the same switch, behind the same firewall, using the same anti-virus, have the same GPOs issued from the same domain controller.
