Well, I can't actually get the patch to install - when I try and do it from the launcher, just clicking on "Update Now" causes the game to shut itself down every time. When I downloaded the patch from here to try that instead, I get this error message, even after restarting the computer:

Actually, I can't get it to uninstall either - the same error pops up. Any ideas about what is causing it? My brother said that it's some kind of corrupted file and then waltzed off leaving me not much clearer.
