I installed the newest Timefactor beta on my unit, made sure to back up everything (I thought). the beta installed fine and I restored my presets only to find out that I had to go back and redo all of my global, Aux switch, expression pedal, spillover, whatever settings. What a PITA!!
Thankfully I had written some of the settings down but I don't remember all of them so now I've got to spend time and play around with it and try to get everything back to the way I had it. In this day and age a backup should store everything.
