I am getting the following error when I try and load Mazimzer 7.5 Enterprise.

"DataManager returned an error code of 3020
An unidentified error has occured on the 'Column" file.

Thats very weird?!!!

I just tried to restart Maximizer again and it started OK???

I have done nothing to the system and yet it appears to have fixed itself?

I would still like to know what is causing the error in case it happens again.

Thanks

From pervasives website, the error means this:

3020: An error occurred while loading the MicroKernel

You receive this status code when an error occurs while loading the MicroKernel or when access to the server and client machine shared memory objects are unavailable. Check the Pervasive Event Log (PVSW.LOG) for more information.

Basically means for some reason it couldn't read the database. I assume this could be due to anything from a network outage to corrupt files etc, however seeming that a restart of max fixed it, I would just assume it to be a glitch.
