I recently updated my Magix Photostory DeLuxe which included Travel Maps. The Travel Maps opened and two of the categories were automatically activated but I cannot access the middle category (40 Premium Maps artistic maps). I have tried the “Activate Content Package” but it says that my Serial Number is invalid. I have also tried “Free download” but it’s impossible to tick any of the items. I should be pleased if you could help me in this regard. Thank you.
