In the TOPAZ.ini file, change the version number to the version of the TOPAZ update you ran.
For example:
I updated TOPAZ to 1.7.7.1 from 1.7.5.4. The ini file still says 1.7.5.4 as the version.
Change the version to say 1.7.7.1 and save.
Open TOPAZ.
If this fails:
Replace the control and company database files with blank ones, re-enter the company information,
run the reset serial applicaiton and re-register your TOPAZ.
