Just my 2 cents but seems to me you could ask your "friend of 30 years" to try whatever it is that you want to try...or go use his machine if he lives nearby.

Also, questioning biab's return policy and suggesting that they offer a dumbed down demo seems counter-productive. If you can get the FULL program and return it for a refund...which you can...it just doesn't get much better than that.

Best,
