You might know already, but since you seem to be new to Poser,... just in case: If you are on Mac, you must convert the files in order to get Poser to work with them, which can be done with the Poser Maconverter tool from FreeStuff/Utilities. On both platforms, the files must also be placed to certain locations inside the Runtime folder. There is another Mac tool which does it for you (Macinstaller), otherwise look into your manual, or look around here - it is explained in a lot of threads. Otherwise, just let us know here, and sure someone will explain it... Welcome to Poser! :-)
