I had the same issue running FactorLIb (with TimeFactor) in Windows 7 – the presets seem to load, but the program doesn't end. It worked fine in Windows XP.
It also worked in Windows 7 with a third party SysEx program called MIDI-OX. This allows you to initiate the dump from the system menu of the XFactor, where you can select exactly what it is you want to dump – in this case, ALL is probably safest. I haven't tried restoring presets from MIDI-OX, but it should work…
I see it is based on Qt libraries – is there a Linux version?
