Cliff notes: User downgrades computer to xp because his wireless dont work under vista, user copies itunes folder and puts it under the new xp itunes install in the right place, it worked but then reset and most every thing is lost including £20 of itunes store apps. Question: If I go through I itunes recepts and then redownload all the things I have bought will I get charged again or is it smart enough to know that I have I have already purchased say, motochaser (game makes me sick ha). I saw there was a back up option to disk but like if you have a large libary and no dvd burner what can you do? What is the recommend way to save you libary, could I have just installed it under XP and ask it to import from Ipod to laptop? Thanks very much.
