yes, yes i have!
just check the SH box as per the first reply.
I found that i could get very well aligned in about 20mins. enough to keep a star centered in a 7mm EP (8" f/6 newt) for quite some time before it started to drift.
my trial expired too tho and i havent done anything about it. great proggy tho
its good for those that cant actually see the scp because of obstructions.
