Is there a limit on file size or number of files? I just tried to load 4 files at 111mb each (8 bit) but it closed down. Tried fast, slow and no alignment but no luck. I think the photo world is crying out for an HDR program that works (at least better than Photomatix - which I reluctantly use sometimes) so good luck with your efforts.
EDIT: tried just 2 files, some pairs worked, others didn't. Of those that worked, sadly, the results were way short of photomatix using the enfuse setting. To be fair, I need more time to play but the controls are fairly simple and don't take long to master. Repeated encouragement: keep trying, I'm sure many will wish you well!
