Need to burn audio book from Audible.com to CD! Help please!

I am somewhat comfortable with computers, but I am new to this new audio stuff..please help me, I was able to write a music cd, and so I wanted to have a book....So, I downloaded a book from Audible.com and I was wanting to put it on CD's for a long road trip tomorrow. I have windows media player, but it keeps telling me that it doesn't have the rights to do it, plus I can't find what I need to copy it to the cd. I never knew it was going to be this difficult, I have to leave at 3am and it's a 6 hour drive...is there any way I can get this done? I don't understand why it's so hard? I want to listen to this book in the car on the road trip, not on my computer???Help please...I really don't want want to spend $80 on the program from Nero that it looks like I need, as I am not going to be doing this all the time and it's only for personal use...Thanks in advance...Candace
