...Are you the guy whose machine Sam and I played with in Brisbane at the BSG Open Night last year?
Nope! I haven't been near Brisbane for a couple of years, sadly... I am based in Munich. I am the guy Richie(?) met at LMP in Germany for the post-Plasa Clarity console preview. He suggested I contact the Safenet directly for help, which I did. They sent me some more drivers, but they didn't work either, after which they seemed to lose interest in me! I must follow them up again.
In the meantime I have purchased a spanking new MacBook Pro (Late 2011 model) with as much Ram, disk-space and screen as I could afford and everything is working fine!
So I guess it really is an issue with my old MacBook Pro - Late 2006 model.
All the best
