iPhoto 9.6 upgrade photos gone only "old master"

I was forced to upgrade to iPhoto 9.6 when I upgraded to Yosemite. Now when I open iPhoto, all of my photos are gone. I know they are not completely gone, because I was able to find them when I opened package contents. However, everything is not under "old".

I had my library stored on an external hard drive (1TB) and I have 223GB of photos. When I click on the library it still shows that amount. I held down "option" when I opened iPhoto and tried to redirect it to my library, but only the "Library.iPhoto" showed up and I have a feeling all of my pictures are in the "Library6.iPhoto".

I tried holding command and option to rebuild the thumbnails and then rebuild the library, but nothing happened.

Has anyone found a solution to this?

I do have a time machine connected to my computer, but I am not sure what good it will do if this is a forced update by Yosemite. I'm stuck.
