I've got the 2.06.1 skin viewer.  I've tried re-installing it to no avail.  It's the same as before--it just doesn't work at all.  When I launch it, I get a small, blank white window and that's it.  It just quits responding after that.  As noted, this only happened after the 2.07.2 patch came out.
AH2 itself gave me a similar problem when the 2.07.2 patch came out.  It did exactly the same thing.  However, I just ran the patch .exe file again and now AH2 works.  However, the skin viewer still doesn't.
