Please verify that you have:

1) Verified the checksum of your update.zip with the HTC ADP website checksum list.

2) You waited after uploading the update.zip file to the SD card as mentioned in the Troubleshooting section.

It almost sounds like a problem with not waiting for the upload of the file to complete. Alternatively it could also be a bad SD card.
