Lutron Homeworks Illumination Please Help

Hi,
I have a Lutron Homeworks System, but the local dealer has disappeared and don't have any other dealers in my area.
I am a software programmer so have experience doing this sort of thing with other systems and devices. Does
any one know where I can get the latest version of the software? So I can get the rest of my house working.

Thanks,
Daniel..

Thankyou everybody for your help, I have finally managed to get my hands on a copy of the Homeworks Illumination Software.
What is the latest version? The version I have is 1.62.

Thanks, looks like the install must of been done with 1.64, as they had started setting up the Home+ App. Does anyone know where I can get 1.64?
