James, from the limited information here, it sounds like mythfrontend is 
unable to connect to mythbackend, so it actually exits with error before 
it gets around to updating the plugin schemas.  If you could post the 
full (uncut) log output of an attempt to run mythfrontend (here or to a 
pastebin), I can look it over and see if it provides more information.

Oh, and just because they're the first few items on the support team 
checklist ;), are you sure a) that mythbackend is running properly, b) 
that you've properly set the IP address for the master backend, and c) 
that your config.xml and mysql.txt files are all correct (regardless of 
where on the system they're located)?

Thanks,
Mike
