Sorry you are having problems.
You can go to the bugsite <
https://bugs.launchpad.net/hugin> where you can
see if there are any reported bugs which are the same/similar to your
problem, and if not make a new bug report.
Probably a good idea to include details of where you obtained the hugin
binary that has the problem; the type of images you are loading (jpeg,
tiff 16 bit, ??), and what software (if any) was used to produce those
images.
Cheers,
