Elements file extention how to open in Premier Pro?

I started work on a video editing it in Elements and I saved the project. I was now hoping to open the project in Premier Pro but I can’t see it in the open folder. The file extension that it was saving in Elements is not an option to open in Premier Pro.
What can I do to get it to open in Premier Pro as I have spent a few hours on the video with Elements and I don’t want to redo all my work?
Thanks
Vic
