Good morning!
I've tried to upgrade using my key, but with no success. Upon program start, I go to Register, enter name and key, then OK. It tells me "Thank you for registering" and quits. I then restart the program, and it takes me to the entry screen, but says "Trail over", apparently not keeping the key.
I've uninstalled and reinstalled several times, also cleaned out the registry of anything called "imagecomparer", with no difference.
All help is appreciated.
