Get this. I HAVE emptied the folder. There is NO visible info inside the nameless, immovable folder. The info that was under Runtime within the folder was good. It installed to the new copy of Poser I installed. The new copy of Poser runs fine so far. I am just left with a mostly empty Poser 5 folder(the one that wouldn't work), and a weird, empty, nameless, immovable, undeletable folder within it. As I said I ran viral scans upon it when it was full and it shows up clean. I have never heard of such a thing. I may give a friend in IT a call this weekend...
