Any dvd

I had the full version of any dvd on my PC, something happened and I couldnt find it so I thought I could just download it again and use it cause I had the full version but it says I have a trial version.
Is there anyway I can find out my registration number so I can have the full version again?

Try this

Also, might want to try this, although this was posted before Slysoft started their own site.
