Hm it sounds like Poser can't find the actual obj file. In that case it will show up like that. It's still listed because the lines in the cr2/pp2 are there.

Take a look in the actual file and see where it wants the obj to be. And then check that it's there. It may have been corrupted - or deleted by accident :)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
