Ok, so did you (or we) make a custom database translator file (the xml file in the databases directory) for that driver? Or do you have a specific one selected?
Off the top of my head I don’t know of specific changes in the translator format from 4.1.5 to 4.2.x, but I’m thinking that’s what’s going on. If you have a custom translator or know which one its using, attach it here or email it to support AT inductiveautomation DOT com.
