I told him twice php, so not sure where he's getting the asp.net stuff from. I told him it didn't work. SO...then I just got this response:

Brianne,
I apologize. We installed a test version of wordpress and we were able to resolve the issue in the wptest subdirectory.
We have now applied the fix to your main directory.

I just tried it and it now works... SO, I'm assuming the fix is in the article link they posted above. Thanks for all the help. Hopefully this will help many of you too.
