If iScrapbook, Business Card Shop, Labelist, PrintLife, or Greeting Card Shop can't open your iPhoto library, it may be corrupt. iPhoto provides built-in tools to repair itself. Here's how:
a) Quit iPhoto, if it's open.
b) Hold down the Command and Option keys as you click the iPhoto icon. The Photo Library First Aid window opens.
c) Select Repair Permissions to repair permissions and unlock necessary files and folders.
d) Click Repair.
e) If the Repair Permissions option doesn't solve the problem, try the other options as well.
If iPhoto's built-in first-aid tool don't solve the problem, then there's a chance that it's because the AlbumData.xml file inside of the iPhoto library is corrupt. If it is corrupt, you'll see an error message that looks something like this:
Couldn't load iPhoto library because an error occurred: Error Domain=NSCocoaErrorDomain Code=3840 "The data couldn’t be read because it has been corrupted." (Unknown character '(' (0x28) in <integer> on line 93429) UserInfo=0x100863200 {NSDebugDescription=Unknown character '(' (0x28) in <integer> on line 93429, kCFPropertyListOldStyleParsingError=The data couldn’t be read because it has been corrupted.}
Fortunately, it's fairly easy to repair this type of problem. Here's how:
a) Quit the Chronos product you're using (iScrapbook, Business Card Shop, Labelist, PrintLife, or Greeting Card Shop)
b) Quit iPhoto if it's running
c) Switch to the Finder
d) Locate the iPhoto library you're having troubles with
e) Control-click on this library file and choose "Show Package Contents"
f) Locate the file inside of this package called "AlbumData.xml"
g) Drag the "AlbumData.xml" file to the Trash
h) Launch iPhoto
i) Quit iPhoto
j) Launch the Chronos product you're using
k) Open the Photo Browser. Your photos should appear correctly now.
