PROBLEMS WITH THE IPHOTO ACTUALIZATION

after I up date mi mac, I couldn't actualize the iphoto application because when I try it say "These app's already assigned to another Apple ID and will be available in the shopping list that Apple ID. If you do not have access to that Apple ID and you would like to receive future updates, you need to purchase applications." and then appear an other message that say "The update is not available with this Apple ID" So what should I do, it's very absurd to buy it, if the mac comes with it.

can anybody help me please?
