Where to get help with GarageSale 7?

I was so happy with prior versions, this is a backward upgrade (paid too) I find it a really poor interface with a couple of unresolvable issues (shipping fees - gave up) and then I find out my scheduler didn’t upload because of some picture error - but it went up OK as a straight upload.

Is it possible to ditch 7.0.7 and go back a couple of clicks I wonder?

I think this will always be a problem whilst GS stays in Beta mode for so long. David
