Having had a chance to read other topics on related forums, I now realize several things!
Firstly, I'm sure that I have downloaded the 'Plus' version of this software, on a trial basis, which is not what I had intended to download.
Secondly, it seems it is very difficult to download the 'Free' and 'Basic' version, as the screen switches extremely quickly to the 'Paid' version within a matter of seconds! This happens so quickly that it is either extremely bad programming, or pretty 'sharp practice'!
As the software itself is really good, I suspect the latter. Which is very disappointing. But I suppose it is a sign of the times, that companies feel they have to resort to this sort of thing, because they know that anything with the word 'FREE' in it will get a lot of views.
They do say there's no such thing as a free lunch.......and there's no such thing as 'free' software either, as the time spend in repulsing the exhortations to buy the paid version becomes such a pain that you wish you'd bought it anyway!
And I do have some sympathies with the unfortunate 'Dr Varney' [ who posted elsewhere on this site] who realized somewhat belatedly that he was dealing with a bunch of 'sharks' !
That may, or may not, prove to be my experience too.
We shall see!
