Perhaps you had better try to redownload the file from a mirror location (there's a link to an official Simtel mirror list on the download page).

The file you downloaded is possibly still saved in a location called the 'cache'. If you choose to redownload it, it'll instead fetch the file from that cache because that is faster that redownloading it from the Internet again. Normally this would be fine, seeing as the file you want to download again is exactly the same one, from the same location. However, seeing as the file is corrupt it'll also give you the corrupt file from the cache again. To redownload it again from the Internet you should therefore use a mirror location (so it won't see it as the same file and redownload it completely) or clear that cache. In Internet Explorer, to do so go to Tools > Internet options and click the button that says "Clear Files" (or similar wordings).
