Nothing on your old computer is salvageable?
If the Hard Drive still works, you can connect it to your new computer and copy the downloaded Powerdirector files if you had them on the old computer. There are USB external cases that you can use to connect a hard drive to the computer.
The next time when you have the Files downloaded, I recommend that you burn a CD or DVD of the downloaded files and the CD Key Email.
It you have a CD or DVD of the downloaded files you can insall Powerdirector from that.
