Cant open project

Trying to make an app for school, but now I cant open the project anymore, when l click on it just shows a loading message and nothing else happens.

Please help, thanks

This URL allows you to open AI2 to the Project List, without opening any project.
http://ai2.appinventor.mit.edu/?autoload=false
From that list, you can request Exports of Projects without trying to open them.
Upload the troublesome .aia here.
