]You did not enable the server's PowerScheduler++ plugin...
Well it's ticked in TV Server config and I can edit the settings there. I don't think there's anything else I can do to enable it.
I've just checked again, but for some reason it doesn't seem to be working as it's not generating any messages in tv.log.
EDIT: No worries, I think I've fixed it now I uninstalled PS++ and checked and saw that the PS Server and Client plugins in the MP folders weren't the 1.2.3 ones (I don't know if this was the case before uninstalling PS++) so I deleted them both and reinstalled PS++ which seems to have done the trick.
