iPhoto don't open, what should i do?

My iPhoto don't open!

It says:

Turn to the appropriate developer over to guarantee itself that iPhoto with this version of MAC OS X is compatible. They must perhaps again install the program. Install additionally available updates for the program and Mac OS X. (translatet in dashboard)

I can click Ignore or Report
