Yes I did update the firmware twice, if I recall.
Yep, the factory presets are there in the file list and I have 2 presets in the setlist, which are the 2 that are onboard the softstep - fully functioning, thankfully.
I figured that one possibility would be to start writing the presets from scratch, although I actually did that with the second preset, that I originally thought may have caused the fault.
I have tried to send a factory preset to the SS and got the same crash = LED 0 stays RED and the message LOAD stays in the Name LED display and the software freezes - ie windoze message says Not Responding.
Anyway, all my stuff is in cases until a few hours time when I'll take another swipe at this. If it fails again, will try with another computer just for the hell of it. Thanks for yr help.
