Welcome! But sorry it's about something like that!
I don't think you're screwed, but it might not be easy. Of course try to "eject" a few more times (just the regular way, I wouldn't try anything adventurous). They probably still won't come out.
And then take it to the dealer. If you're anywhere close to your first (or next) servicing, just mention it to them when you bring the car in for that -- and I think they might even get out the CD's for you without charging anything extra, or maybe just a bit.
Don't take this as any final word. Let's see if any of our tech-marvels say something else.
