Where to get Adobe flex 2.0 SDK?

Hi All,

I am a newbie to flex and working on very old flex application which is built 8 years back. I am trying to revive that application. I tried to use flex SDK 3.0 but it failed with below message.

Error: Could not resolve <mx:AdvancedDataGrid> to a component implementation.

It seems it  needs flex 2.0 SDK? Any idea where can i get it? or Is there any other option available to resolve above error?

I tried to google and found few reference but nothing is working.

Below is one of them. But for this person it fails while running. In my case it fails at compile time only.

FlexCoders - Could not resolve <mx:AdvancedDataGrid> to a component implementation.

Thanks in advance.
