Combo Update v1.1 (Intel) Problem. NEED HELP!!!

[bach]

hi guys, i am about running Vectorworks (CAD Program) on my mac, but after i installed the Program, i can't run it.
Then i called customer service from Vectorworks, and they said that i need to install Combo Update.
My problem is, when i try to install the combo update, MAC OS refuse it and said that

"You cannot install MAC OS X Combo Update(Intel) on this volume. This volume doesn't meet requirement for this update"

FYI : i've fresh installed my OS 10.4.10 (with backup dvd), and come this problem.
sorry for my bad english, anyone can help?
thanks.

Are you talking about the MacBook in your signature? Does anything show up if you run Software Updater? :)
