After turning off compression for the zip mime type all is back to normal.

For anyone who has downloaded anything from the store recently, you may want to go back and download it again.

It's actually pretty amazing that no one has e-mailed or contacted me about it.  I have had several people download the Free CSS Editor recently and if it didn't work why wouldn't someone say "hey, I tried to download your free module for DotNetNuke, but it seems to be corrupted".  Oh well.

Here is a good setting example for the Blowery HTTP Compression settings if you are using it in DotNetNuke:

<blowery.web>
   <httpCompress preferredAlgorithm="gzip" compressionLevel="high">
      <excludedMimeTypes>
         <add type="image/png" />
         <add type="image/jpeg" />
         <add type="image/gif" />
         <add type="application/zip" />
         <add type="application/x-zip-compressed" />
         <add type="application/x-gzip-compressed" />
         <add type="application/x-compressed" />
         <add type="application/octet-stream" />
         <add type="application/pdf" />
      </excludedMimeTypes>
      <excludedPaths>
         <add path="Install/" />
      </excludedPaths>
   </httpCompress>
</blowery.web>
