NxCharacter.dll load fail

I recently bought Dragon age origins ultimate edition off of steam and downloaded it, when I ran it I got an error that said "library load fail: NXCHARACTER.DLL".

I thought that it must be a screw up on steam so then proceeded to download it on origin and still get the same problem, I have now downloaded it 3 times and am still getting the same problems.  The furthest I've got is an error box saying that there was a problem with the games setup and asking me to reinstall my game.

Again, not particularly helpful.

Lots of posts suggest it's an antivirus thing, I have my antivirus ignoring the origin games folder and I still get this problem (my antivirus is Microsoft security essentials)

Please help me fix this, I have downloaded 60+Gb's of data with nothing to show for it and on a 200KB/s speed that is a lot of wasted time.
