Thanks for all the suggestions. I've traced most of the cr2 problems to bad paths in the cr2 files. It seems that Poser is still able to load these files even though the paths are completely wrong (!) which is what threw me. Some files using relative paths still don't load, though. Transposer still won't load more than the simplest .pz3 file. I suspect that this problem is related to the outstanding one with the cr2s. Eovia's offers of help were immediate and reassuring, as were the comments on this forum. I'm more and more impressed with this product and am swiftly becoming convinced that I can figure out these last issues. I expect I'll be buying Carrara. :-)
