Plugins not showing up anywhere!?

Hey guys,

So I've downloaded 2 more plugins for my WPMU site, Anti-splog and Blog Widget. When I install them, I get a success message but when I go to Sites to add the plugin to only my site, the plugins aren;t there to chose from. I can't even chose them from my Pro Site > Premium Plugins! I look at plugins and they are their but they are Network Deactivated.

Any ideas?
