Ok I didn't think it would be a space problem even though I free up a bunch of space. Still no luck. Went into the Poser 5 files and found at the head a folder that HAD NO NAME. I didn't think windows would allow this. Furthermore, it could not be moved, named, or deleted. Inside of it was a runtime folder with accompanying sub folders that all looked OK. I ran a viral check and came up with nothing. My fix. Reinstall Poser to a new place on the same drive. Barebones it opened fine. Added my runtime folder. Opened fine. Copied anything else except the mystery folder, opens fine. Now I just have to figure how to get the damned empty, unnamed,, unnamable, undeletable, unmovable folder off of my computer. Cheers, RWB64
