What version of WinZip do you use? If you are using a very recent version, it could be that MoHAA can't read it? Zip is not always 'forward' compatible (I don't think you can extract .zip's made by version 8 with version, say, 4).

By the way: I use WinRAR (3.11), to make my .pk3's, works fine. Can handle all kinds of extensions. In fact, I like it better than WinZip, which I used to use. KaZaA.
