To correct the "Failed to create empty document" in Hallmark Card Studio 2005, delete the PLANR32.DAT and PLANR32.BAK from the following default directory:
C:\Documents and Settings\All Users\Application Data\Sierra\Planner
Once they are deleted, the user can re-launch Hallmark Card Studio 2005 without having to reinstall. Users will see the Child-Lock screen when the program is first launched.
Note: Existing users will lose any Address Book and Calendar settings for the Event Planner. This shouldn’t be an issue with new users.
