Yes ! I spent my first week refining the setup, only to lose the whole thing. After that I couldn't get the system to work the way I wanted again, until I sussed the problem.
If you only program the TC1000 exclusively with the software everything is OK. NEVER learn a new code, or delete devices etc on the remote first. Do it all with the software and it seems to remain stable. The only exception is adding a new device, which you have to do on the remote. Accept any manufaturer suggested if yours dosen't exist and then re-learn from the software. Don't use the TC1000's "skip" button if you must learn a device. This seems to cause problems when the data is merged.
All in all this is a real pain, but my solution is good. I've been stable for over two weeks, making almost daily changes, with no loss of buttons or settings !
