Hi, this afternoon, while I was working on another project I clicked to My Stuff and open up an older project. The linked open up but the project was empty, no scripts or sprites. I saw in another discussion thread that there was some type of bug and one of Scratch support team was able to restore the projects affected by this bug. I was hoping that my project could be restore as well, as It is part of my CCOW Design Notebook. Here is the URL: http://scratch.mit.edu/projects/2444454/

I'm sorry that you had this problem, but thanks for reporting it. I was able to restore your project.
