Well I hadn't opened my iTunes with Windows XP in a week or so after syncing my iPhone, but I just added pics to a folder syncing with my phone, so I decided to open iTunes, sync and go, but when I opened iTunes, it was empty! No library, no purchased music, no apps etc. I'm 99% sure I still have all the music, but Its like my iTunes is starting fresh. What should I do? Would a system restore work?
