the main thing is to make sure the files are in the right location. For example the .cr2 file needs to go under the Poser4/runtime/libraries/character subdirectory along with the .rsr of the same filename. .pp2 are pose files. I have a very good (not a tutorial) one page figure for you to look at. It'll show you where to put each kind of file. Also, always keep the zip file and the readme will then be with your stuff. Usually the readme will tell you where to put it. After a few times you'll get the hang of it. Just hang in there it'll get better :)
