Microsoft.Jet.OLEDB.4.0

I colocate my trading copy of NinjaTrader 6.5 at a VPS hosting facility.
Today, when I tried to open my colocated NT application for the first time, I received the following error:
"Unable to connect to database 'Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;DataSource=C:\Documents and Settings\Administrator\My Documents\NinjaTrader 6.5\db\NinjaTrader.mdb': ObjectSpace: Connection String is Invalid - Unrecognized database format 'C:\Documents and Settings\Administrator\My Documents\NinjaTrader 6.5\db\NinjaTrader.mdb'
I reinstalled the software, but this did not solve the problem.
Any ideas about what could be causing the problem?
Thanks

You're likely dealing with a corrupted database file here - did you try closing NT down and then renaming the NinjaTrader.mdb file in the MyDocuments > NinjaTrader 6.5 > DB folder?

Would you then be able to restart normally?

Yup, renaming the mdb file sorted the problem. So, corrupted database file ...

Thanks.
