I updated to iTunes 8.1 on Thursday night and looked forward to trying out the new features. What it concealed however, was a whole host of problems that would plague me for the next two days. After updating iTunes it crashes every time I try to run it. After clicking report the problem seems to be: Code: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00000000076ff040 I gave up trying to resolve this after a few hours (because Google hasn't told me how) and set about restoring my previous incarnation of iTunes. After locating a copy of 8.02 (my Time Machine is disabled atm) and installing it I was told that it couldn't open my iTunes library for it was created by a newer version of Windows. I then option clicked the iTunes icon and loaded up a previous library, which incidentally only seemed a few hours old. Running 8.02 worked fine for the few hours it was good for. I turn the computer on today and for some reason iTunes cannot open the library because it was created by a newer version of iTunes. I option click again to reveal that my choices of previous libraries now range from one created yesterday to one created over a year ago. Selecting yesterday's library yields nothing as it was apparently created with a newer version of iTunes. As far as I can see there are two solutions: 1. Fix iTunes 8.1 2. Create a new library for 8.02 and drag/drop the iTunes music folder in there Obviously option 1 is a much more sustainable option, I want to be able to upgrade my iTunes in the future - i'm not going to want to be stuck on 8.02 for ever. Option 2 however is probably a better short term solution - I need to sync my iPhone for iCal synchronisation etc.. Any suggestions?
