Hi,

Your post says that the problem is on a client computer,.

But the error message says that it has been installed as the server ("main computer").

The screenshots show the AC utility trying to find database files that don't exist on the client computer.

***

If this is the case, I'd uninstall AC completely from the client computer, using Revo Uninstaller.

Then I'd reinstall it as a station, not a server.

Cheers,

Carl Fogel
