When I opened Sound Packager 10, It froze up and became non-responsive, so I closed it and tried again, with the same result. So I was forced to download and re-install my old copy of Sound Packager version 1.31. However, when I entered its Product Key, it gave me an error message which said "Invalid Product Key/Serial Number", although I was careful to enter all numbers and letters completely. So I tried changing my e-mail address, but then it gave me an error message "e-mail address not found". So I tried off-line activation, but that didn't work also, so now I am stuck with a trial version of my purchased Sound Packager ver.1.31 software. I thought that when I purchased Sound Packager ver. 1.31 several Years ago, the Serial Number/ Product Key would be valid Forever! So please help me with this Problem of Mine.
