You can't. The "Out of memory" is just Poser's way of saying: "Something is wrong, I dunno which way is up. Bye" When you deleted all objs textures and so on you may very well have deleted something vital for that very file. Poser gives the Out of Memory error typically if it can't find the obj for whatever you're loading. It just puzzles me that it happens to a DAZ item. Their stuff usually installs correctly...

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