The only thing I can think of (if there is a problem with the skin) is that its getting corrupted during the download.  Every time though?  Skuzzy verified it on their end.  I believe it if he says its ok.  You only have a problem when that skin is displayed.  I believe it when you say that also.  But whether the issue is the skin itself or your machine's rendering of that skin that causes a problem, I suppose the point is moot.  Maybe your video card is allergic to that skin.
