MaxDB Database Studio - Internal DB no more coming up

After a reboot of the system where DBStudio is running the integrated database doesn´t come up again.

Trying to start the instance manually just leads to a "Database could not be started, this happend already 5 times" entry in the windows event log. Since I couldn´t find a knldiag (or knldiag.err) I wonder, how to recover from that situation and find out, what the problem with the database is.

Database Studio

Version: 7.7.03.18

Build: 018-123-160-639

Any ideas how this can be drilled down?

Markus
