CDR 2021 crashes when attempting to activate?

I have uninstalled/reinstalled the program multiple times and even redownloaded the installer several times, but every single time I've tried to activate CDR 2021 the damn program crashes. This is the order of events. I install the software, open it, click the button to activate it, enter my serial number, hit activate & then POOF the Corel screen is disappeared in a cloud of smoke. I try it several times w/ the exact same results then uninstall the damn thing and try again by starting from the top. 

Help please! I've had CorelDRAW since v.3 and I have never encountered a problem like this when upgrading. I'm at wit's end. None of my colleagues have had any issues when installing 2021 and they claim it's their favorite version in years. I'd love to make that judgement for myself but it's very difficult to do when I can't activate the program. Looks like I'll be sticking to using my trusty 2020 until I can resolve this problem.
