IChat AV on Leopard now working

Question

thanks to Ralph's message and bhagemann's reply, iChat AV/Leopard is now working for me.
I'm going away for a while and I have been trying to get iChat AV working reliably so that I can video chat with my wife while I'm away, but every attempt to connect to/from outside resulted in the same dreaded 'no response' error. Skype works but iChat AV is so much better.
I did indeed at one time have Sharing/Internet Sharing turned on and shared via Network/Airport, but I don't generally need Airport on my iMac and had therefore deactivated it. consequently, the Sharing/Internet Sharing option was not checked and I wasn't aware that my iMac still had two IP numbers assigned to it. after reading bhagemann's reply, I reactivated the Airport network service, unchecked Internet Sharing, deactivated the Airport network service again and tried 'chatting' with [email protected] again. no more problems, at least for now ;–)
thanks guys. those two messages (after searching and trying various things for hours and hours, and even a couple of complicated calls to tech support) really helped.
sincerely,
Gregory

That (9C010) is the bit that says you have done the Time Machine and Airport Update and this takes your OS beyond (Above ?) the actual point that the 10.5.2 Update gets you to.
This is why you have the message about the OS not being suitable.
You have a folder in /Library (The one you can see when you open the Hard Drive) that has a folder called Receipts.
With some downloads you can fool the OS into thinking it had not done it by removing the item's .pkg
I do not think this will work in this case as it is not the only Check Software Update or the Installer makes on the OS and Packages.
I understand from EZ Jim that if you do have the Time Capsule it come with an Install Disk that Must be used before you can set it up fully. I don't have one and was unaware of this until yesterday late my time.
The only sure way I know to do this in your position is to do an Archive and Install from you Base Install Disks of Leopard and then do the 10.5.2 Combo before doing the Time Machine and Airport Update.
It may be possible to popen the 10.5.2 Combo with Pacifist and use that to Install it but I have not Tested this.
