Spyder2Express problem creating a profile

I've been trying to calibrate my Oct 2005 rev 15" PBG4 with Spyder2Express v2.3 -1 using the default settings of the setup assistant and each time after going through the colors a "Sorry there was a problem creating the profile" error occurs. Is OS X 10.4.11 not compatible with Spyder2Express or is it something else that is causing the error?
