I have created several projects in Premiere Elements 11 using Gopro footage. After publishing projects to my desktop I was able to open and view all projects. I then moved the published version, the PREL version and all asset clips and photos to a folder on my external hard drive to avoid loading up the hard drive on my laptop. Now when I go into the ext. HD and try to view the published version I get a message indicating the file type is not supported. And when I attempt to open the PREL version I gets messages asking where are certain clips, photos and/or rendered versions of the project. Can anyone steer me in a direction that will shed some light on why this is happening and hopefully provide tips on how to correct it. Thanks in advance for any help given.
