Mine didn't hang, but it stopped and gave me an error. (I'm not at home now, so I can't tell you exactly what it was.) I have also gotten the error trying to load other cr2's such as a number of AsShanim's products. I will let you know the error when I get home and check it out. Was going to email you, but just never seem to have the time. I think off-hand it was some sort of out-of-string error, but that may be from something else, I'm not sure.
