iScrapbook 4 on the Mac App Store is a sandboxed application and stores it related data in a special container located at the following path on your computer where ~ denotes your HOME folder:
If you're a user of earlier versions of iScrapbook or other Chronos applications like Business Card Shop, Labelist, SOHO Labels, or SOHO Business Cards, then you might have a collection of iScrapKit artwork on your computer. In the past, this artwork was stored at the following path:
~/Library/Application Support/Chronos/iScrapKit Library
When the Mac App Store version of iScrapbook 4 launches the first time, it is required by Apple to move your iScrapKit Library inside of its special container at the following path:
~/Library/Containers/com.chronos.iScrapbook/Data/Library/Application Support/Chronos/iScrapKit Library
This means if you launch an earlier version of iScrapbook or other Chronos products, they will not be able to find the iScrapKit Library where they're used to finding it. This problem can be solved two different ways:
1) You can upgrade to Business Card Shop 4.5.0 or later, or Labelist 7.5.0 or later. These versions are compatible with the sandboxed version of iScrapbook 4 and thus know where to find the new iScrapKit Library. Please note that there is a $25 upgrade fee if you're upgrading from SOHO Business Card 1.x - 3.x to Business Card Shop 4.x. Likewise, there's a $25 upgrade fee if you're upgrading from SOHO Labels 1.x - 6.x to Labelist 7.x. Here are the relevant upgrade links:
2) If you don't want to upgrade, you can manually COPY the iScrapKit Library file from its new location to its original location. The downside to this option is that you'll have two completely independent copies of your iScrapKit Library. If you add kits to one library, they will NOT be automatically added to the other library and vice versa. Plus, there's no way to automatically merge the libraries later on.
