Please note this is for folks that are having issues with the non nav update.
Just loaded the update from Ford without modifying the download. Here's how (please proceed at your own risk):
First I used two USB drives one 8GB and one 32GB (you could use one but you will have to reformat in the middle and wait for the files to copy)
1. Formatted both drives to FAT32
2. Load the files linked on post 18 of this thread to the 8GB drive:

3. Load the files from the ford update download to the second drive.
4. Start the car plug in the drive with the mem error fix files and let the update proceed (took about 5 to 10 min).
5. Wait for notice that the install is complete then shutdown the car, remove the drive and reboot system.
6. You should receive a notice that the update was successfully installed.
7. Shutdown the car again.
8. Start the car and plug in the drive with the official ford update files.
9. Wait for notice that the install is complete then shutdown the car,
LEAVE the drive plugged in and reboot system.
10. You should receive a notice that the update was successfully installed. You can verify the version in the auto update section of sync.
11. Now this part is optional but you can take the drive and complete the update registration on the my ford site.
