Sometimes problems can occur in the RTG Bills or RTG Timer database. The cause might be a hardware problem, a software crash, or even a bug in RTG's software.

Certain problems are easily fixed with software that you can download by following the instructions on this page.

One such problem is the error message Invalid use of Null, which may occur when you try to edit a matter, fee, expense, payment, or adjustment. It also may occur when you try to view or print a bill, a prebill, or a report. When you click OK in response to the error message, RTG Bills exits.

This problem occurs when a record in the database contains bad data. A field in the record contains Null, which in database terminology means that the field was not given any value.

A few other problems can also be fixed by this software. RTG will refer you to this page if we believe the software described here can solve a problem for you.

You will install a small program that fixes bad database records. It puts appropriate "default" values in the fields that now contain Null. It also checks and may repair several other problems.
