I'm going to try downloading it on another computer and see if that works.
Edit: It still says "invalid file" on the other computer.
I just unzipped it on my desktop and it worked fine. I would upload it for you but I'm in a hotel and have terrible connection.
Also, you said you are getting a clean unrooted evo after reboot, which sounds like my problem I had this morning and I had to download the radio update and run it like you do the rom files. I applied both the radio update and the rom at the same time and all seems to be working now.
