The list of cameras supported is by default at Program Files | Kolor | Autopano... | Resources | cameras.txt.
I have found versions of 5/08 and 3/08 the do include an H1D. Perhaps you could look at the cameras.txt file you have installed.
Another approach is to load some images in a lhs group in the APP main window. If you click on the Settings Icon, the one with the pointing finger, your images will be listed. At the bottom is a link to email@example.com. Clicking on that generates a file you could send to the developers. It could well help to do that: also escalating your problem.
What you described does sound like an unsupported camera by dcraw, but there is one problem - you said it happens with TIFF files too. Can you post a screenshot? Also if you upload those 4 raw files and 4 tiff files somewhere (e.g. www.divshare.com ) then we can take a look.
