Upgrading the code is easy. there is a video on the STERN site which shows how to do it step by step.
When there is a gamecode update Pete, if u have any hassles, u can call me and I can easily talk you through it. You just have to make sure u download the WinZip program which is also on the same STERN gamecode page.

Wow, u have your music even higher than me, your neighbours must love you by now.lol   

you dont need the WinZip program, you can just copy and paste or extract to your nominated drive
same result either way
