I am running MoneyDance on a PC with windows Vista. The program was working OK but when trying to start it this morning it came up with the error message ‘cannot open main class’. What does this mean? and how do I correct the problem.
I am not sure if connected but we have also had problems Outlook, yesterday, the PC prompted for some ‘urgent’ driver updates which I allowed. After finding that I couldn’t open Outlook, I restored the computer to about a week ago.

We have also been having an issue with the registration on this version of Moneydance after transferring it from one computer to another, so this could also be part of the problem.

    I suspect that if you transferred the program from one computer to another rather than downloading the software again and installing it this could be the cause of the problem. I recommend that you make sure that you know where you moneydance data file is and that it is safe. This file has a .md extension. Then uninstall the Moneydance program. Then download the latest version of the moneydance program including java from our website and reinstall it. If that doesn't help let me know and I will investigate further.
