Until this afternoon FB worked without any problems. But at once the FB
Server has been stopped and I saw, that the service is not running
anymore. When I tried to start the service, I get the error:

'Could not start the Firebird Guardian - DefaultInstance service on
Local Computer'

'Error 193: 0xc1'

I have uninstalled and reinstalled FB, but I always get the same error.
Any ideas, what can cause the problem?

Regards

Guido
