This out of memory message is often caused by Poser not finding a texture file where it expected to or finding a jpg instead of a bmp or bum. The answer to this is to put them in the right place or convert them to the correct file type then try reloading the character. Sometimes (I have found this with pz3 files) they work fine the first time you load them up but when you go back and try to open them again they give the out of memory message. In this instance go into the geometries folder and delete the rsr and let Poser build another one. Hope this is of some help.
