morning. shrink tunnel controller, 1769 l33er, studio v32. downloaded a change last week for the new film, ran fine. tonight the tunnel blew its breaker, electrician reset it, controller came back up and my change is gone. it's running the program from back in march, the recipe screen even has the old film names.

second time this has happened. first time we figured somebody downloaded the old file by accident, but nobody did tonight, i was standing there. went online and compared and it's definitely the march version, and downloading my file again fixes it until the next power cycle i guess.

is the controller memory going bad? i don't want to redownload this every time a breaker trips. what am i missing
