It's been a while since I ran the diagnostic/reset procedure, but I don't recall any difficulty at all, and I simply had the instructions printed out in front of me - followed them to the letter. I don't recall having to wait too long though.
I suggest you send an email to Lexicon, or call their support line. Just spell out your problem and see if they can help. They're generally responsive (though not as much so as some companies I'm familiar with).
