Jetpack

I just can’t seem to install Jetpack on my server.

I’m able to Network Activate:
Jetpack Gravatar Hovercards
Jetpack Markdown
Jetpack Post Views

But not:
Jetpack by WordPress.com

When I try to Network Activate it, I get the Fatal Error:
You tried to access the address http://bitesizecanada.org/wp/wp-admin/network/plugins.php?action=error_scrape&plugin=jetpack/jetpack.php&_wpnonce=d52ee70a9b, which is currently unavailable.

If anyone can help me, I’d be eternally grateful. The main reason I’m doing this is that I like Jetpack on my wordpress.com blog, and would like it on my server’s WordPress. Plus, I really want to post my tweets on my server’s wordpress.

Thank you all in advance,
Tk
