Security update error

I'm trying to install Facetime on my iMac but I keep getting a box telling me I don't have security update 2010-005. I've looked in System Preferences/System Update and it shows the update being installed on Aug 24 2010. I've downloaded the update and tried to reinstall it multiple times and rebooted multiple times. Face time continues to say I don't have the update and won't install. Also when I click check for updates it says I'm up to date. I can't seem to find anyone else having a facetime problem. Any suggestions? Thanks

Try reinstalling the update.

I have. Many times as stated in OP.

You do have 10.6.4?

Think I'd wait it out a couple of days or maybe even head to the Apple forum to report the issue.

It is a beta, so I'm sure they're aware of some issues.

Just downloaded it here - the unpacking locked up my whole machine for 10 minutes.

I'm having the same issue, I tried re-installing as well and got the same results.
I'm gonna give it another try now and see what happens.
