First, thank you both for your help. I noticed that in the data folder that one of the folders is i13 Estate Agent and the other just 13 Estate Agent. I was thinking that might be one of the problems but not the reason for the stretching of the mesh.  And in the readme there is no mention of the pmd, just this file belonging in the data file

RE_Pants_11796.dsf

I don't see any mention of the pmd file when looking through the duf file in notepad++. I have redownloaded DSON (was thinking I might have needed a version update). Will post after I've updated it.

None of the PoserCF should even be referencing the PMD file. That file is auto-generated upon first load through the importer (and any subsequent time if those auto-adapted files are ever deleted). Either use the script hborre linked to above, or if you use Daz Studio at all, just create a new set of PoserCF for the pants. I wonder, if you opened the CR2 for the pants, if there's more in there than the version and runpythonscript lines, because there shouldn't be.
