Power Excel users, help me please

Here is a file that I would like to run in Numbers if possible... numbers crashes every time I try...

I get an LS Compatibility error every time...

okay, it won't let me upload an .xls file for whatever reason...

Does anyone know how to resolve this?

 

De-duplicate iPhoto library... (with a couple thou pics)

My iPhoto library has a bunch of duplicates... to many to sit and delete each one..

Does anyone have any idea on a simple approach?
