I had to take my computer back to factory specs and need to re-download any dvd
Ok, here’s where you do that: http://www.slysoft.com/en/
You’ll need your key as well. You should have saved a copy of the key somewhere, so all you need do now is copy it onto the hard drive and double click on the key to get it into the operating system registry.
If you don’t have your key, you will need to contact Slysoft and give them some information, including the original email address you used before, so that they can send you a new one.
