For clarification, I downloaded the Anime Doll Kit from Renderosity. I said StudioMaya because that was the company that made it. Sorry for the confusion. Anyway, it seems like the pp2, lt2, rsr, cr2, and obj files that I downloaded are not able to be read by P4. I did notice a discrepancy between the file types that I downloaded and the file types of the files that came with P4. The files that came with P4 are shown as "Poser 4.0 Document" when the files from Anime Doll Kit are shown as "Text document".
