I have made and of course saved several highly edited (for me) projects and want to put them all together into 1 long movie. They will all open individually, but I can't add them as media. This is my first adventure with adobe it's all gone well until it was time to pull it all together.

Always good to say what version of Premiere Elements that you are using and on what computer operating system it is running.
Where are these prior individual creations coming from and in what format do they exist? Do they all exist as individual Premiere Elements project files (project.prel) or have they already been individually exported to a file type or disc (DVD-VIDEO or Blu-ray disc format)?
What is your intended type of export for the grand project that will contain all the individual sources of media?
