I purchased the program on 21/11/2014, and if I understand it the update to version 2015 was free, now if I try to do the upgrade from StampManage Deluxe 2014 tells me that my program is updated to 2014, however, . How do I upgrade to 2015? You need to download the demo version in 2015 and enter the code of the purchase of 2014? Roby
