iTunes has recently stopped working and closing on me every time I sync it to iPhone 4... It gets to music part after backing up and box pops up saying there is a problem and iTunes has to be closed.. I havent done anything different to either one for this to have happened.. Might be latest update I have installed on phone.. Anyone else had problems like this or know what it could be?? I have reinstalled iTunes and I have restored phone to try elemintate problem....
