That’s a very old version!
Any particular reason why you’re starting out with such an old version?
There’s an “archive” somewhere for “legacy” products on the main SiWi site - but the easiest thing is probably to speak to your local Distributor…
Searched and searched, nothing found, i downloaded some newer software to the fastrack, but it`s gone with the blast wave. Bad software. Probably must go to china now… 
Did you ask your Distributor
