For many years I have been using MZ-Tools Add-in features from time to time. Today I wanted to use line numbering in some code in my module and the add-in won't work. When I try to set it to load on startup and reopen it says ""MZ-Tools 3.0 could not be loaded. Remove it from the available list of add-ins?". It could be that it hasn't been working since I upgraded to MS Access 2013 several months ago, but it surprises me that it's taken me so long to realize it. I looked on the web site and not that version 8 is now being offered for about $80. Is there a way to get my old version working or do I need to buy a new version?
