There is something wrong with the latest downloaded installation as Malwarebtyes rejects it. Googling for answers, many are complaining of "Candyware" or something named like that. The consensus is that you are now including adware which nobody wants, many are looking for alternates.
This is a trajedy as this is such a great program to have to give up. Not only that, I have donated to help in the work you have done.
I suggest that you remove the adware garbage. If you wish to have funds again, solicit for more donations, or put the program up for purchase and require a registration.
Just my simple minded thoughts!
