This may be a bit further advanced than where you are, but Acadia made a really good point about getting an understanding of the Poser runtime file structure. Meaning: where all those Poser files live, in which folder, and what sorts of files should be in there. I remember having the wrong type of file in a ... say, hair folder ... and then looking for it under the hair library. Turns out it was a .cr2, not a .hr2 (the type of file is described by the file extension).

Oh, and to commiserate: Daz's file system nearly drove me to drink. I couldn't figure out what was where was what in that system. It reminded my of later versions of Windows: in an effort to make things easier (the Desktop at the top of the hierarchy tree thingie, for instance) they confuse much.
