If you'd have or give the full unabridged litteral error message, it might be possible to google it (put quotes around it, add "ms money" and see what comes up). But that won't work now.

MS Money isn't part of MS Office, so this is more or less the wrong forum. Try PC Applications or Computer Help.

I don't know MS Money, but as I read the message could it be that you configured the old program to code the data on the disk to inhibit intruders to read them? Then you would need to provide the same code here, somehow. Just a WAG.

Hope you find the solution.
