HELP: iPhoto won't open my library !

[legaleye3000]

I was on Mountain Lion. I backed up my iPhoto library and restored it once I downgraded to Snow Leopard.

When I try opening iPhoto it states, "You can't open your current photo library using this version of iPhoto." Anyone know how to fix? Thanks!

I think your problem is files outside the iPhoto library that are created by iPhoto. I know that with iTunes there's more than just the iTunes directory under Music, but I'm not sure what's involved with iPhoto.

I looked in the ~/Library, but couldn't find anything connected to iPhoto.
