Circus Ponies Notebook for Tiger and Leopard

[Bunbury]

I own a license for Circus Ponies Notebook version 3.0 and I use it everyday on Leopard.

But when I tried to run it under Tiger, it failed saying it needs Leopard. 

I can't find an older version on the Web. 

Can someone point me to or send me

- the last version working on Tiger 

- the last version working on Leopard

I'd appreciate it! Thanks
