When I try to start TV or radio in a Client-PC There is allways error on connecting to Database.
I have tryed to open every possibillity for access, but without success . Same result with all Firewalls closed.
What have I missed? In earlier versions there where no problems.
Thanks in advance for some hints.

Kind regards
