Thanks for the reply. I'm hoping you will be back in Texas sooner rather than later. I'm still fighting a Commerce Starter Kit site that was due two weeks ago due to this medium trust issue.
I assume that the .zip file contains your actual medium trust configuration for use in testing. Unfortunately whenever I try to download the file I find that the .zip is corrupted. I've tried from a couple different machines.
If it is indeed corrupted can you please repost. Otherwise can...
