Hi Adam
I see that you have posted this same issue before - our response is the same.

If you are using Cashbook 6.5B, it is compatible with G/L V6.1 - 7.0A. Although it is unlikely that this issue is due to Y2K compliancy, I am not familiar with the release date on your version of G/L though - you should check it for Y2K compliancy, as well as the version of WSM you are using to ensure that proper Y2K ptfs have been installed for these ACCPAC Plus apps. Cashbook became Y2K compliant with the release of V6.5B (981118), which implemented 4-digit year dates. The current release of 6.5B is now (010509)!
