No, I haven't changed a thing. In fact, just to make sure, I actually phsyically went into each and every one of the folders where my supposedly unopenable files are, and made sure that they were there, and intact. Despite this, apparently Poser doesn't seem to recognise them in any way, shape, or form. I have absolutely no idea what the hell I'm supposed to do. On a related note, by going through the Control Panel and using the Add/Remove Programs utility, I did manage to uninstall and reinstall Poser. With the same result. I'm getting really annoyed.
