Glad it helped..... but
This tells me you have inadvertently mucked up your drive permissions on those drives, and that the System User cannot access these drives. While fixed for Serviio, this may give you ongoing issues with other programs, so you may want to address the underlying issue - Google is your friend (restore drive security permissions).
Should be non destructive but backup your drives just in case.
