Opening .swf Files per Default with Flash Player

[Tigger]

I really have to watch my words right now, cause Mac OS X is driving me mad with something really stupid:

I did a CD with Flash MX a few days ago, and made a Projector with Flash. No somehow this has changed the default application for .swf to exactly this Projector, which is of cource useless to open them.

Now if I change the application for a .swf to the Flash Player SA, it works, but if I press the Button "Use as default..." (or whatever it is called in English, I use the German language), it changes back to the Projector for the CD.

This is f...ing drivung me crazy!

How can I make it use the Flash Player as default again, or how can I even get rid of the Projector inside of the Open with... menu?

Please help, I am desperate here.
And on the verge of throwing my Mac through the window...
