I omitted the name of the product that you used, but paying 50 bucks for software that made an image file and gave you no way to transfer it to a new drive doesn't seem smart. We certainly don't want to provide any promotion for such a product.

Knoppix can do copies with the dd command, you might want to look into the documentation on that. I don't really know if it will do what you need though.

You might also want to look at the great utility ISObuster. Even the free part should allow you to extract the files from an img file and copy them to a new drive.

I would also think that you should be getting feedback and support from the people who sold you a $50 utility.
