Sprites and scene disappearing

Hi when I saved my project and open it again everything saves inculding events, but my sprites and the scene disappears meaning my all my .PNG files are no longer showing then I have to add them everytime. Imagine if I have more levels I would have to do this for each one. The scene also freezes then I struggle to edit at the same time nothing will work when that happens. I would really appreciate your help thanks regards Denzil Klaasen

Wow is anyone going help here please?

This project seems like hell.
I think the only reason is that the path of images is no longer the same.
Open the image manager above the scenes. Then look at the difference between the paths.
When several GD projects are opened, only the first one is saved.
