Managed to get hold of the 4.11 software and a windows PC running Windows 7 32 bit.
Thankfully the software recognises my Beo5 but I can't seem to get it to do anything. I click in 'create' and it creates a profile, but it never leaves that main page.
Its been years since I did my first set up of the Beo5 but I'm sure once you clicked 'load' it took you to a new page where you start the process of setting up zones/rooms and telling it what equipment you have etc.
Any advice would be appreciated
