Hopefully someone can help me here.

The recent update to USKP (v1.3.3) has been reported as causing this issue - go grab the latest version with the hotfix (v1.3.3b).

whats the uskp and where do I get it from?

Damn nexus wont let me get it....I use the nmm.

Give it another try, Nexus has some connectivity issues right now but the download should work.

I just tried a heck of a lot and it keeps saying server unreachable.

The problem may be because you're not using my Hunting mod

j/k lolz.

Isn't the USKP available from TES Alliance and Dark Creations also?

Yes, there are 4 locations you can download the Unoffical Skyrim Patch. http://www.gamesas.com/topic/1467323-relzwipz-unofficial-skyrim-patch-thread-34/.
