What version of Premiere Elements are you using and on what computer operating system is it running?
What is the brand/model/settings of the camera that has recorded your video? What type of a connection have you made
between the camera and the computer - USB.
What happens - by any chance have you gotten to the Add Media/....../Video Importer, and the Video Importer is not showing your
camera in the Source field?
Have you tried to transfer the video from the camera to a computer hard drive location and, from there, import
that into Premiere Elements, using the program's Add Media/Files and Folders (versions 11 and 12) or Get Media/Files
and Folders (versions earlier than 11).
The answers will be in the details.
We will be watching for your follow up.
