Ok, so it's not just happening to me. I wish I saw this thread before starting my own! It's actually less than an hour until closing, and I have that same partial blue load bar.
I think that maybe if you would just let it sit and load for a while, it will eventually come up. After waiting about 15 minutes it finally went through and when I came back to my computer it was up and running. So if anything else, just give it some time to load while you go off and do something for a little bit, and see what happens when you come back!
I had same problem and had to clear my temporary memory to get in. Once I cleard it and started again it worked fine,. My blue bar kept getting stopped about 15% too.
