Strange.
I've downloaded the template myself and unzipped it, and ran it with Photoshop. It works fine.
I think it's either a corrupt download or a WinZip problem. Try the download again, and unzip it with latest Zip programs. If it still doesn't work, I'll send the templates via email.

The Fw190A-5 uses the same textures for the wings as the Fw190A-8. It's named that way too.
