[Urgent Help Needed] Activity Monitor keeps crashing

[xira]

my activity monitor crashes as soon as i launch it and writes this to the crash log:
http://rafb.net/paste/results/cnFe6559.html
the file GraphKit was not there, so i got someone to send it to me, i put it in that location to no avail

i have tried repairing permissions

i have tried deleting the plist

i have tried replacing the .app with someone elses

this is my first problem on my mac, so i'm very emotional and nervous right now. any help would be appreciated.

Update:

I put that file in teh wrong dir, putting it in the right dir solved the problems
