Sounds like the files arn't filed properly within the Poser Runntime folder. Make shure to read the "read me" files that come with the stuff you download & follow the directions as to where to file the parts. Sometimes there is no such information & you just have to wing it. When you try to load a newly downloaded & converted "thing" & Poser says "can't find . . . " then write down the info in the pop-up window. It gives you an idea of where it should be & what the name of the thing is that the cr2 is calling for. Then do a search in the finder on your OS to find the "thing" & drag it to the folder Poser expects it to be filed in. Sometimes a texture (or object) has been re-named after the cr2 was written, once in awhile a lower case letter has been changed to a cap. Poser isn't too forgiving on things like that.
