and in the Notepad you have:C:/Documents and Settings/Ob-1/My Documents/maya/scripts/GI_Joe.mel line 59: File not found.
so first of all, you dont have a Ob-1 where the user is supposed to go, then you are missing a \ RIGHT after Documents...and why doesnt maya Show the 4.5 folder??C:\\Documents and Settings\\My Documents\Maya\\4.5\\scripts\\GI_Joe.mel
