Heya guys, I'm a total noob so forgive the rediculous questions. I've been loading up some of the zillions of free downloads lately, and have run across this problem a few times. When I go to the Render Materials link and try to add a texture/bump or reflect map that it should have but doesn't list as showing, I get a message saying:

"There is already a texture loaded with that name" and it won't let me load it. So here I am looking at my reflect area and it says 'none' but it gives me the above message when I try to add one.

So what's happening in the Poser brain and how do I fix it?
