Serviio Windows Service Randomly stops

So the Serviio Service in windows 7. on THIS PC. keeps stopping. from in a few hours, to a few days. I just now tried to open the console with an error 500 and it said to check the log.. this was in the log, so I assume, it was part of the issue.. Serviio on my other PC works, and runs just fine.. i just updated Java on this PC.. and just updated all the windows updates, but this problem has been going on for several weeks.. anyone have any idea on how i can fix it?

  Code:

Weird, looks like the database engine has problems accessing the database files. Check the drive, access rights, etc where Serviio is installed.

Yeah it's the C Drive, and has full access to the drive..
odd with this error, if i restarted the console it would open. but have no folders listed.

but if I closed it. stopped the windows Service for Serviio. then restarted it. opened up the console. they were there, and it all worked.
