If you're still using Creative Memories Memory Manager and/or Storybook Creator, now is your chance to UPGRADE to Forever software.  Historian is CM's Memory Manager equivalent and Artisan is CM's Storybook Creator equivalent.  All four software were written by the same developers.  So, your existing memory vaults and photobook projects, as well as your digital artkits, are 100% compatible with Forever's software.  As long as you have the artkits activation codes, you should be able to transition to Artisan with no problems.
