Clicked on Notice to Update DVDfab and now it won't work

I purchased DVDfab about a month ago. It worked fine until I received a message that new version is available. It kept popping up in the middle of my using my existing version until I finally clicked on it and downloaded it. Once downloaded it now tells me that I have 10 days to use or purchase the software again (although it is the supposedly updated version). Worse yet, when I continue to try to use it, a message keeps popping us asking me to send user information. I sent the requested information. But the message still pops up and keeps me from using the software. I ran a virus scan but it was negative. I don’t know what else to do.

just unistall it and then download the latest version 5.2.5 and install it
