My guess is that it is the usual problem of not having good starting estimates. Before you do anything with your images, run CheckReg with a selection of the images and one of the MNI-space images released with SPM. If the images are poorly aligned, then things will fail. Orientations should be within about 15-20 degrees, and the positioning should be within 3-4 cm.
