Answer 1

The NHibernate support people just pointed me in the right direction to fix this.

The problem was that IIS didn't have permissions to access the windows\temp folder.

I went to the IIS AppPool > Advanced Settigns > Identity

And changed it to LocalSystem (since I'm the admin on my PC). That fixed it for me. Hope this helps.

Answer 2

Can you try with the latest build?
