Hello.

After having to stop and restart the Windows XP firewall to solve (I wish) a problem with PowerScheduler plugin, I have detected an error with database.

It happens in TVServer. The error occurs when the TVServer is started (when Windows start). I have obtained the log file attached by just running "MP logs collector", starting MP and closing it. But the error was already there.

The error.log file in TVServer log folder is:

2009-03-12 00:20:18.828125 [TVService]: Exception   :Error: DatabaseUnavailableUnclassified
Gentle.Common.GentleException: The database backend (provider SQLServer) could not be reached.

2009-03-12 00:20:27.062500 [TVService]: ss2: Tuner Type failed:0x91000001

I have installed twice MP, following the manual and without changing anything related to DB (MS was selected).

I don't know if this error could cause a malfunctioning in MP, but I have notice nothing wrong. But the true is that I have just installed and I have not used it a lot (just the TV).

Any idea on how to solve this?

Thanks.
