Moved from Photoshop Elements forum.
If Premiere Elements 9 wasn't installed with an Adobe serial number, you may well have gotten a limited edition version that Dell threw in for free. Unfortunately, you won't find any support from Adobe if this is the case.
This is a pretty old piece of software and it isn't even compatible with a number of current video formats. But, assuming you're still working with tape-based HDV or miniDV video, your best bet may be to buy an old copy of version 9 on Amazon or from eBay and try a re-install. Though even that may or may not work, since there are a number of components that may no longer activate.
I know you say you like this classic older version, but I really think the liabilities of getting it up and running are far outweighed by the benefits of upgrading. Even if you just upgrade to version 11 or later (they can be had relatively inexpensively), you'll find so much better performance, ease of use and support for current formats like AVCHD and smartphone video.
Steve – Thanks for your response, and your right, the app is six revisions down. I am not sure why the file(s) in my PE app became corrupted, but your response did convince me to dump the app and move on.
