After reinstalling Video Deluxe 2021 Premium the tool still import MTS files, but crash trying to export or viewing them. For many years it worked. I opened a ticket to the support and the reply was "program version you are using is no longer supported by our support team. Therefore, we are unable to provide technical assistance for this product."
Is someone able to help me? Is it possible to stop supporting a program only after 5 years?

I just updated the hardware to move to Windows 11 after changing the hard disk.
