not displaying project file

I posted this to the Cardbide3d support but thought I would ask here as well.

I was trying to post a project and was getting a blank screen where the carbide create file was supposed to be displayed. I finally gave up and deleted the project and was ready to try again.

It was then I noticed one of my prior posted projects had disappeared. The odd thing about that is when I log into my account I can see the previously posted project.

Suggestions on what I am doing wrong is appreciated.
