error remoting wmp, empty list and WMP error

[Bert]

Markus, you're right.
The following error message comes up in the server_debug:
remoting error: System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: The system cannot find the file specified

As per your email question, if the MCC is been launched when I just start WMC: yes, the add-in is been started and when I minimise WMC it has started MCC as well in background.

I will try your suggestion tonight and uninstall MCC server and the Add-in including deleting the folders %localappdata%\MCC Addin and %localappdata%\MCC_Server and also delete the three task schedules in regards to MCC. Afterwards I install again and see if that fixes the problem...

Thanks for that, I'll report back here...

Cheers,
BERT
