Blog not Loading, Cannot Create New Posts, Dashboard is Still Working Though

Looking for any advice.

I am unable to open my blog and not sure why. It does not load and times out every time. http://www.throughyourbody/blog

I am using Lunar Pages to host and have called and talked to them and they have yet to resolve the issue although they did up my domain use for free.

I most recently updated to 2.7.1 prob about 3 weeks ago and until yesterday I could post,etc. The only thing I did yesterday while posting that was different was deactivate my twitter tools plug-in.

A couple of things that might have caused this:

I have had an e-lancer updating my theme which I lost when I switched to 2.7.1

I have posted several videos on my blog and my signature is a pre-loading video on the end of every blog post.

Any other thoughts/ideas as to why my blog is not loading properly? My website which in on the same server is working fine. I’m open to any and all ideas. Anyone else had this issue before and resolved it?

Thank you!
