Looks like the version changed around 2006 to 2008 time frame. Peter, what's different about Version 2.0... and the one I bought 1.0...? Do I need to buy latest version or will the upgrades you listed here on your web site work? The reason I'm concerned is that I bought a used Dell Laptop with Vista, and the program doesn't seem to be working properly. When I turn on the train style and push a key to get a riff playing, it sounds broken up and distorted and the tempo seems to be slowing up. I loaded and re-loaded both discs but that didn't help. Any suggestions?
