This may caused by the setting to "no affine registration", although I have tried this combination without any problems. However, I would try the default settings in VBM5.1 (center-of-mass approach is default) and check the normalization results for any mis-registrations. For those cases I would manually set the AC in the display tool or try to coregister the images as proposed in another mail. All these steps are intended to roughly align the image to the template to provide a good starting estimate.
