IPhoto crashes since downgrade to Lion

Question

i recently upgraded my system to mountain lion and hated it so much that i downgraded back to lion.  in the process, i had to reset my user password.  after this everything seemed fine...until i tried to open iphoto.  i have tried reinstalling from a disk that i have from when i first bought the computer.  i believe it to be the most up to date version of iphoto (not that i can open it up to find out).  I am on a MacBook Pro OS X 10.7.5
this is part of the error I am getting, any suggestions for how to fix this?

Answer 1

Can I literally just copy it and place it into the private frameworks file? what would be the process for going that route?
Yes you can copy the Prokit.framework from the System/Library/PrivateFrameworks folder on the other Mac to the same folder on your MBP. 
You will need admin privledges on both machines in order to do it.  After putting the framework on the MPB run Disk Utility and repair disk permissions.  Then reboot and launch iPhoto.
