I purchased a Space Helmet Prop, but I can't get it to load. I install it in poser, but when I try to load it from the library I get the following message; "No disk in drive/please insert a disk into drive/device/harddisk2/dr4" Then every thing locks up, and I have to shut down Poser. I tried reinstalling several times. but everytime I try to load from the library, I get the same "no Disk in Drive message" and it locks up. Any idea what the problem might be? Am I doing something wrong?
