Don't know since I'm not a developer.

If you have downloaded the file from Apple, then you have your developer log in and you might want to try Apple's developer forums - link.

If you've downloaded it via torrent, then that could very well be your whole issue.

i have a developer log in id and i have tried apple forums
and i have downloaded it from-

w.developer.apple.com (outdated link removed)

help m guys @!
