Does anyone have a reliable copy of this file?  I procured one to upgrade my Chelton system a couple of months ago and it trashed the entire program making the Chelton unusable.  I got someone to restore it and upgrade it,(was told the file I used must have been corrupted) but I have another IDU that now needs to be upgraded and am looking for a good clean copy of the upgrade file.

Ideally I would love to get two copies from different sources to compare to be more confident the upgrade won't produce the same result because of corruption.

Thanks,
