I had a lot of trouble getting my site up and running and kept getting "Required permissions could not be obtained..etc etc" The problem is that the Microsoft.Practices.ObjectBuilder.dll in the code download is not compiled to run under medium trust, and many hosting companies (including mine) insist on medium trust. Solution is easy - download the latest version (1.0.51206) from www.codeplex.com/objectbuilder.

Should have found some clever way to get it to update itself from somewhere?

My new TBH based site is at www.shivag.co.uk - check it out, and let me know if you find bugs or (Hopefully not) security holes!
