Problem updating Apps w/ App Fresh since SL

Since I installed Snow Leopard I've run across a couple problems:

I use AppFresh to keep my apps updated. Since SL upgrade, have been unable to upgrade X11 (tells me its for Leopard users only.), Flip4Mac WMV (downloaded & installed but when I run AppFresh, tells me I need to update like I didn't do anything), and WMV Player(same as Flip4Mac).

Also, have been unable to Change iTunes icon to my old Soviet iTunes icon like I used to have w/ Leopard.

I know this is alot of stuff, but Does this seem like a problem with AppFresh itself? Anyone else having these problems? Suggestions? Answers?

Thanks in advance.
