My channel unavailable in Canada? Must be a simple oversight

once you upload a PKG to the channel store, as either a private channel or unpublished/published public channel, the "Package" link it displays has a .zip extension if you try to download it. If downloaded, it isn't a valid zip file so you'd need to rename it to be .pkg. If you're following so far, be sure the file you upload is a .pkg file, not a zip file, and hopefully roku can fix their back-end server to not rename it to an incorrect .zip file extension sometime....
