Error Code 20506 - Invalid File Number.
This usually occurs when the program shares a printer resource with 2 reports that have a different number of files assigned to them to output. This bug should not occur in version 1.3j or above. If it does, please report it immediately, and please let us know what report you were attempting to print.
FIX: Because it is a confliction within the report generator all you need to do is exit out of the program, then run it again. Then go right to the report that erred, and it should print OK. Under extreme cases you may have to reboot and try it again.
