Hi,
This issue has nothing to do with our VM Template. Our VM Template doesn't have any influence on TABLE names or such that.
If you "google" this error code, you will find lots of results, this means, people are suffering from the same issue even though they don't use our VM Template at all. We are responsible to resolve the issues only if they are related to our VM Template.
Check this URL:

and do the guy suggests:
"Did you back before upgrade?
Go to tools-> Tools and migration -> Install or if necessary update tables
Cheers.
Flexible Support TEam.
