Registration window pops up whenever I start ProgDVB!

#1
I am a registered user of ProgDVB, but the registration dialog pops up whenever I start ProgDVB on my Windows PC. I set the correct key and details and click Activation, and then it tells me to restart ProgDVB, but when I do that, the same window pops up again. How do I fix this? Must I reinstall it?

I did try to reactivate my registration, but that did nothing either...

It says Trial (-1 days left) when I clicked activation.

I am using the latest version.

How do I solve this?
