Hey Paul,
Using 3.6.2 here.
Getting started make sure your stars are roughly focused, you should be able to get the first light wizard working after this.
Make sure you have the log window open so any errors can be easily spotted.
Look out for Max HFD warnings, Max exposure warnings, Flux values.
These all can be seen and changed in the Setup and Features tabs.
If successful first time with the first light wizard, you'll create one profile routine, go next 6 times, till you have enough profile routines to use for your autofocusing. From there on you have the enjoyment of using 'select', or 'focus'(auto star select) to start focusing
If you do hit any errors; just post them, Im sure they are easy to work out. Once you get use to the program it's a breeze to setup again.
