unable to upgrade to iPhoto 9.5 version. is there a manual download somewhere?

Hi all

I have the 9.1.4 iphoto version that suddenly stopped working. Now when i click on the software update for the new iphoto 9.5 version it refuses to download. i get a message that tells me the following" these apps were assigned to another Apple ID, and they will be available in that ID's purchase list. If you dont have access to that Apple ID nd want to receive future updates, you will need to purchase the applications."

The message before that was that i need to log into the Apple ID i used to purchase this app. I did not purchase this app to begin with. It came pre-installed with my Mac Air. because i did not recall the password to this particular ID ( I assume its the ID they are talking about), I requested a password recall by inserting this old Apple ID. the password never came although it accepted the ID as valid. As for security questions, I probably wouldnt be able to answer it given that it was a long time back.

To summarise:

I did not purchase this Iphoto App version 9.1.4. It was preinstalled. I got 1 message that tells me i need to log in to the apple ID I used to purchase it when I got it pre-installed. this message was recently replaced by the newer message i directly quoted above" and now I have 75GB of photos in my iphoto library that I cannot access because it seems the OS X software I have is to advanced for this version of Iphoto. can anyone help?
