HELP!

I really need some help you guys! I can't publish any posts for my blog from the blog site (Right now, I'm posting this through "BlogThis! - Google Chrome" helper thingy. Anyways, for some reason every time I click on "new post" from the site, it goes to the correct page, but then the text box continues to load. I am unable to type anything into the dialog box! I refresh the page, but that doesn't help. I close out the window, restarting my access to the internet; but that does nothing. I've tried to shut down and restart my computer, and to be honest all that does is delete my desktop background/wallpaper image.

Please Help Me, I'm not and don't know where I am!
