I bought some e-books of teaching resources several years ago.I saved them on a portable hard drive but neglected to save the security keys I was given with them. My laptop died and I have no record of the keys or where I purchased them so I am unable to open them. What should I do?
Contact the seller and see if they will supply it again. Adobe do not keep your keys on their system.
Trouble is, it was 5 years ago and I can't remember where I bought them.
I cannot see any hope in that case.
