Not really sure why my previous reply is not getting displayed.
I strongly believe you have issues at the DB side.
Like I have suggested before have you tried to connect to the MaxDB using the MaxDB Studio or MaxDB Database Manager?. If not then please try that.
Check the log area and data area from the studio.
The error code rcSQL=-10807 is about connection to the database.
Also check if the MaxDB services are running from services.msc
