... I've got a bit of a problem ... I am trying to add a power supply (5500PS) to a database that I am building in Toolkit 1.9.2. When I try to edit the unit it comes up with an error message: [B]Error 20036 Unit Specification Invalid, please visit the CIS Website ([URL="http://www.clipsal.com/cis"]www.clipsal.com/cis[/URL]) for an updated version of this software[/B] I have 55 other units in the database and can open all of them without issue. Any suggestions CIS?
