try this: install poser 5 again on top of the current install that has your combined runtime folder in it. That way it'll replace any files with the same names with the newer version. The way you did it put the older version on top of the newer. You should do this anyway in case there's fixed geoms for anything that came with p4 (remember the rattlesnake was updated in a patch, etc). just back up that runtime folder to a separate location first, in case the installer blows it away or something horrible like that! :)
