Jmonkey won't load- stuck at Opening Main Window

Sorry, I am new to the forums. I have been using Jmonkey for a class for a couple months without a problem and I open it up today and it is stuck as shown in the image.

I have restarted my computer a couple times.

any ideas?

Sorry I’m not sure the image showed up- here’s a link.image

Fixed: I took my most recent project out of it’s project location, then opened jmonkey and it worked. Then I just put the project back and it seems to be working normally. Strange.
