My girlfriend has been having a strange problem ever since changing her MobileMe password. She has the following setup: Macbook Pro 15" running 10.6.4 with iCal as her primary calendar - synced to: MobileMe - synced to: iPhone 3GS running 4.1. Since changing her MobileMe password all of her iCal data has seemingly been lost. iCal displays none of her synced or subscribed calendars. However, her phone and mobileme's web calendar display all her correct information and are syncing perfectly. The only computer listed under the MobileMe prefpane is her Macbook Pro so I don't think there is a problem with the info being synced to another computer. I have attempted to Reset the sync data on this computer with sync data from MobileMe but to no avail. Would it be worth trying to de authorize her computer from her MobileMe settings and then reauthorize it? Or would wiping the iCal pref file and trying to start from scratch? Any advice would be appreciated. Thanks.
