I think what you are saying is that (as I am using Win10) as opposed to donating I should have bought the Win 10 app - I wish that had been clearer to me.

Thanks

Your link takes me to a page about reviews, I don't think I have ever been asked for a review.

I have renamed 440 files - is that too many?

I am happily using the 'free' version 4.7.9, I get 2 nags, 1 telling me about a new version and 1 after I have converted files saying that I can donate, I decided to donate, it suggested 10 Euros which I did but I am still getting the donate nag.

What was the point of donating?
