I use poser pro on Windows Vista 32 Bits and I am experiencing the strangest problem with my "Props". They are stored in Runtime->Library->Props, where I have 138 folders with various contents. Suddenly, I notice that some of them are greyed out when I attempt to sue them from inside Poser. I tried simply deleting the offending props, only to find that, when I restart Poser, some OTHER props now appear greyed out. I attempted to delete those newly greyed-out props, but then yet other props now become greyed-out. When I tried to empty out all folders and place them back one by one, testing them in Poser in between, all sorts of weirs things happen. The first 69 folders show up fine, but adding more either greys out some specific props or even the whole props option in the Poser menu. Attempts to isolate any "guilty" props individually lead to strange effects where the removal of one folder makes another one get greyed-out in the menu and so forth.

This is driving me crazy! Can anyone help me out?
