    Hi, on almost all of my apps downloaded from the app store I'm receiving the following message:

    “GraphicConverter 9” is damaged and can’t be opened. Delete “GraphicConverter 9” and download it again from the App Store.

    This seems to be a bug how do I resolve this? I'm not downloading all the apps again from the app store!
