MP2 - V2.1 MP2.1 pre TV stopped working ("error invoking GetChannels, GetProgramsGroup") (1 Viewer)

[tlhackque]

MP 2.1 pre seemed to work (I only use it for TV) after yesterday's install excitement.

Now, however, when I launch it I get a red dot with a white X on the client screen, clicking on it gives me the messages (in order)

• error invoking GetChannels
• error invoking GetProgramsGroup

I rebooted the machine (which is painful due to other uses), but the problem persists.

These appear as errors in client.log, and as the following warning in server.log

Looks like the same problem as https://forum.team-mediaportal.com/threads/2-1pre-error-in-slimtv3.135742/

This morning, it's working again. I restarted the service, killed the client in task manager, & restarted the client.

I had tried this several times yesterday with no success.

The machine was idle - except that the Windows task scheduler executed a zap2xml task. This deposits a new file for the guide update to pick up, so I suppose it might have affected a race condition (which appears to be the issue with the referenced bug)... The new XML file is 13.4MB.
