OBJ problem is solved. However, I just noticed that the issue also applies to PNG's (and I am pretty sure they are all located in my "Poses" folder in the Poser 6 library). For example, I purchased "High Fashion Lifestyle-Breezy" made by Pretty3d. The folder came with clothing to put on V3 models. The clothing has shown up before in the past. In fact, every PNG file I have has shown up before, so it doesn't just apply to "High Fashion Lifestyle-Breezy". 

But yesterday I had to do a little "rearranging" with the zip folders since they were not all in my main Poser 6 directory. I also had to extract files that I downloaded as "freebies" from the Holiday Giveaway Week 4. Now, no PNG's will show up in my scene. Maybe it is because of my reorganizing the zip files? I'm almost positive no important files have been damaged.

One last thing, while I was extracting certain files, this message came up: "The files 'License' and 'ReadMe' already exists. Do you want to rename these files?" And the options would be "Yes", "Yes to all", "No", and "No to all". I wasn't really sure what to do so I did "Yes to all". Might this be the problem?

I really don't know how to solve this problem and would like some more help please :(
