Keep downloading. Only z3_virgin1.tib is corrupt.
Any advise for those of us that wound up with the corrupt image on our HDD? I suppose following your excellent instructions in this thread a second time will take care of it? 
I'm guessing that you're looking for instuctions for when you have the new file?
Here's what I did:
Downloaded Magaupload and HTTP overnight. (Experience told me that one or the other might have a problem
)
I updated the Z2 drive in accordance with the great instructions provided here by garrettoomey using the HTTP download.
When I was done Trueimage told me that there were errors. 
I then unzipped the megaupload file from septicdeath and went back to Trueimage - starting over.
This time I only did the "Recover" for the 17 gig map partition using the septicdeath image and called it quits.
Back in the car, everything is working fine. I have the 2008 maps and my music and data is still there. Voice command is working fine.
Now I just have to go back in and get rid of that opening screen banner again.
