Make sure that you are looking in the right folder. If you originally installed Poser from Metacreations the Poser directory will be: C:Program FilesMetacreationsPoser 4 If you installed the Curious Labs version it will be somewhere else, probably in: C:Program FilesCurious LabsPoser 4 My guess is that you are looking in the wrong directory, and that the right one exists somewhere else. Do a search for Poser and see if you find two directories. I do not think what you did could erase your other items, just overwrite existing files of the same name and path.
