iDVD doesn´t open - Image not founds - immediately quits

One week ago, i was building a DVD with iDVD. Everything worked just fine.

But today iDVD immediately quits when i´m trying to open it.

I am running MAC OSX 10.6.8 and installed the iPhoto and iMovie Update yesterday.

The error-message of iDVD says:
