Afrankh,
I happened to keep the lac file (licence) that came with this giveaway just in case I thought I may need it in the future. So to check your theory, I copied the original installation, which I'd backed up on my external and then added the lac file. Created a desktop icon and booted the program up. It works perfectly and says that it's registered to Giveawayoftheday. When I first booted it up it did ask if I wanted to update it which I declined.
It maybe that the program has somehow been updated. Perhaps someone else that uses the computer????
Sorry to hear you've lost the use of it. Maybe the giveaway team will repeat it soon.
Regards
Whiterabbit.
p.s.
check to see if you did copy the original lac file. It may be that the program was never registered, but an extended demo. Adding the lac file would have taken away the demo nature of the software. Can you remember adding a lac file????
