Ah nm, SP2 doesn't support AutoCad 2002, just 2005 version. But seriously before you guys go cusing and b******g at microsoft and reformating just check the software in question website and see if their is a patch or something for it, as most companies have put out patches to correct incompatablites(sp). But still its users fault, you can turn off autoupdate =/
Also why even update it at your jobs? It doesn't really offer anything for the work place. SP2 is more for at home use, better overall security, its a little bit faster, DirectX9c and so on.
