Finder is invisible...

Well, I keep the dock of the side and ended up with the translucent grey thing that looks terrible with 3d icons... I tried to change the finder icon by changing finder.png in dock.app, the finder application itself, and the finder.icns inside. I also deleted com.apple.dock.iconcache. I rebooted and such but now it just looks like this.

Anyone have an idea as to how to fix this?
Thanks in advance.

Did you backup finder.png before you edited it?

No >_<, I didn't think that changing the finder icon would be much more difficult than changing the trash icons so...
