Version 22 breaks my version 4.4 character rig and scene

I am trying to open an existing project (created in v4.4) into the new Version 22. When it opens, all of my character rigs are gone, as well as their meshes, and in the scene, my characters and BG no longer show up. 

Is there any special way to bring an older project onto this new version? Or do i need to finish up my project in 4.4. I would love to use body tracking on this one! 

Thank you for your help!
