I got mine a while back but haven't invested anywhere near enough time in it yet. I've just been using the defualt settings and having a bit of fun with them, but reading this thread is definately motivating me to start playing some more with it and tweaking it.
In the final section of the manual there's an explanation of each parameter, in a sensible sort of order, and it explains what you need to do in terms of setting up the mixers and stuff to get different parts of the pedal working how you want. If you sit down with the pedal and tweak as you read, you'll get the hang of it in a couple of hours.
It still takes a long time to set up a sound, but there aren't nearly as many head-scratching periods as you'd expect. It makes sense.
I've also gotta update the firmware as have had it freeze a few times so glad to hear it can fixed simple.
FYI with the latest firmware mine still hangs occasionally, I get a crash every couple of hours on average and I haven't noticed anything specific that causes it.
