My system has been stable for years. However, my ISY 944i failed (red light on) indicating that there was a problem with the memory card. I re-seated the memory card and the ISY came up again but I noticed that the system light on the PLM was on and as I had a spare PLM, I replaced it and restored the PLM. All seems to be working but none of my scenes work. I've tried restoring the PLM again but that doesn't seem to help,. All the devices that are in the scenes are working fine but none of my programs that trigger scenes work. Also, I can't trigger the scenes from the Admin console. I did a scene test and it failed (tried to upload a copy but it wouldn't work). I would very much appreciate any suggestions re next steps to solve my problem.
