After a few days the issue has been resolved. The support team was helpful but it did take some days to resolve the issue
the problem was that the download link provided when you buy the product, gives you an old version of the software that simply does not work. The support team eventually sent me a link of an updated version and then it worked. I have not yet tested in full the software, i plan to do that on the weekend, but so far everything seems to be in order.
So i would ask the owner of the thread to review this issue, that the download link provided at first will lead you to download an old non functional version of the software, so that in future people don't have the same problem that i have.
i have to say however that the support team was helpful, and that the software (from what i've tested so far), delivers as promised.
