I have Calendar Creator 8 and I am having trouble printing my calendars. If I decide to upgrade my program to Calendar Creator 12, can I access my CC8 data file to install in in CC12?
No, you can't print your calendars in the new version if you use an older version to create them. You can read about this issue on the Support page provided by Encore. Access the page to read more about it.
You can also buy the new version from the same website as well: http://www.broderbund.com/p-116-calendar-creator-deluxe-v121.aspx#sys_req
This happens because Calendar Creator *.bcc files are not backward compatible. - Encore Support
