Scratch

I am trying to upload a project and when I do the upload box comes up but it stays on "Connecting to scratch.mit.edu...".
I've tried exiting and trying again but nothing will work. There is only background images and one sprite, and only like 3 or 4 scripts, so it isnt a big file, but I don't know why it is doing that. It's never happened before because I just uploaded a project not long before this one. So um, help.
