clone dvd

How do I purchase clone dvd when it expires if there is no option on the website to do so?

So I am trying to figure out after copying my with Clone DVD2 how to convert my DVDs to an MP4 file so that I can watch them on my phone and was wondering if any one could help me figure that out? Unless I don't need to convert the file to MP4 to play them, then in that case my question...

I have been using Clone DVD for several years but my PC went down and I lost the program. I have the key Number. Is there any way to use this key and get the program back or do I have to purchase the program again? Thanks for your help in advance billy829
