Manila-D - Of course they're idiots! How else does one refer to those who are reviewing a desktop program on the review page of an entirely separate product?

Contrary to your assertions, his recent stand-alone program certainly does work, and rather well too as it happens. Perhaps you need to 'widen' the group of people you talk to privately...

And a likely reason the Developer hasn't taken this non-working and abandoned Add-On down is the unwary are still sending money in the hope it will be updated or the pro version might still work.

Frankly it's little short of unscrupulous, and isn't helped one iota by numpties here who are still posting daft five-star reviews for this broken product, when in fact they're actually referring to his separate stand-alone desktop program.

There you go... hopefully that addresses your concerns and elucidates matters. :-)
