Make a copy of all the DB*.* files in the VeriFier folder (default is: c:\Verifier) also copy the valcal.ini file located in the windows root directory (typically c:\Windows).

Copy the DB*.* files (Qestion #1) and copy them into the VeriFier folder (default is c:\Verifier), copy valcal.ini file to the windows root directory (typically c:\Windows)

Look in your verifier folder, see if the db*.* files are there. Also, make sure that the file valcal.ini exists in the windows root directory (e.g. c:\Windows)

You may have lost the database alias, to fix that, go to Control Panel, Double click on the BDE Administrator, on the left panel of BDE Admin. look for Instrotek. If you find it, select it and in the right panel under path you need to have the path of your db files (e.g. c:\verifier). If not, enter the path and try to run the application.

If on the left panel you can not find Instrotek you have lost your database alias. To make one, you can reinstall the VeriFier (full install) or simply make a new alias. To make a new alias go to BDE Admin from Control Panel then from the Object menu select New and choose Standard for your database type and hit Ok. That makes a new alias on the left panel. Change name to Instrotek, and in the right panel set the path to C:\Verifier or wherever you have installed Verifier. Try to run the application again.

Reinstall the Verifier program, it may have lost the EPROM Burner program some how.
