Sammy, it's very difficult to try to assess this properly without knowing what you're doing when you receive an error message, what the exact error message is, the version/dates of your software, etc. Try opening sample data (on the same drive as your software in SOFTRAK\APWIN\Samdata) and doing some of the same things you do in your own data when you receive this message. Are you able to recreate the situation? If so, then, it's possible you need to reinstall your AP software.

It might be a very good idea for you to contact your Adagio dealer/consultant.
