Hey there, i`v looked everywhere i can think of for the answer to this, and i`ll probable kick myself when its something simple, but i`ve just put ss4.3 on my computer at work (havent got one at home) and it worked after going and MADACing it all, but it says i need to reformat my HD3, now i already have about 17gb of music on there but its not on this computer, its a collection that has built up over the years in various different places i have been. what should, or can i do, will i just play it saxe and go back to 2.2???
