HI! I need help trying to open my iTunes! I thought it would be cool to upgrade my iTunes to the new iTunes 7 but now it tells me that I need to upgrade my entire system in order to use it! I can't open it at all! I have macbook and I really don't want to have to upgrade my entire system because I only have dial up internet! I know it stinks but that is all I can get and it will take up to (maybe more) 43 HOURS to upgrade! HELP!!!! Is there any way i can go back to my old iTunes? I worked great!! Please help me! Please, Please, Please....Thank you!
