And, yes, as mentioned above, therein lies part of the problem. No backup available from when all was working. (That's the trouble when all was working fine with no changes. You forget to make a new backup.) Would it be possible to edit the recent backup files to remove the pointers that hook back to the previous PLM? That's the only way I can think of to retain the Scene and switch settings, if I am correct in thinking that the ISY is getting confused about the new and the old PLM.

I am having similar problems but I think I have messed things up much more, trying to figure this stuff out. I have a moderately complex set up and I am hoping not to start over from scratch. I have plugged my way through many of the helpful posts and how-to's but am still stuck. So either I have pooched things up severely or I am missing something in the various steps and permutations. Symptoms: some of the lighting/switch combos are still working fine (those that do not need a Scene or Program, eg. switch pairs etc). But I have been unable to restore my more complex settings. Longer description of what I have tried: initially, I thought it was the ISY994 that was on the fritz. I did not catch the importance of the PLM in my brief readings of the forum (stupid me!). Replaced the ISY and tried to restore settings etc before I realized that it was the PLM that was the culprit. I then replaced the PLM, but again stupidly did not follow the proper steps (thought it was just plug/play/swap) so in reconfiguring the ISY, I think I now have a godawful mix of settings between old and new PLM parameters. And of course, the ISY Backup from 2 years ago when all was working swimmingly died on the hard drive 6 months ago. Sigh. So currently, after much messing around, with a much more careful read of the various tips, I am still stuck. In the Main tab on the Admin Console, most of the device names are there, some accurately report current device status but most do not; a few will allow simple commands such as 'Fast On' but most will not. And still none of the Scenes or Programs work. I have tried Restore Modem; Restore Backup; swapping the two ISY controllers and more Restores; and various permutations on reset/reboot order. So, if I understand correctly (and that is a big and doubtful IF), I think that my current config may have a mix of settings. But if it was just mixed PLM settings, Restore Modem should fix that. Since there are lots of devices on the home network, I would rather not start over from scratch. Since most of the basic switch parings still work correctly, I am hoping to be able to read from them back into the ISY configuration. Ideally, I would like to keep the Programs and Scenes or be able to restore them somehow. Hopefully, one of you can suggest a less painful way for me to restore a rather messed up system. If anyone needs an incentive to provide a helpful fix, from what I am reading in the earlier posts above, I am happy to send them my old dysfunctional 2413S, as it probably just needs new capacitors.
