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.
