can't reinstall iphoto after OS X reinstall

My OS X (Lion, 10.7) install recently got hosed and the good folks at the Genius Bar wiped the hard drive and reinstalled it for me. I had transferred all the data to an external hard drive. I had bought a new version of iphoto when I upgraded to Lion awhile ago (downloaded from the app store, so I don't have any disks). I thought I'd be able to download again, but now the version in the app store requires Mavericks (10.9). I would upgrade to Mavericks except

1) I'm worried that just like the Lion upgrade, in the end I'll end up having to purchase upgrades to other software applications I run

2) I know for sure that right now VMWare Fusion 5.0.3 which I use to run windows, so that I can run MS Access does not work with Mavericks

Anyone have any ideas that don't involve me paying $20 to talk to an Apple rep ? Is there any place where I can download the correct version of iPhoto. I probably have the original version of iphoto that came with my macbook on a disk somewhere, but my recollection was that it didn't work with Lion, which is why I purchased a new version... Thanks for any help!
