Hi Jniz,
I am not quit sure what problm you are having, but here are the steps for burning a CD.
After you CLICK on the 'Burn CD' icon in the Action Window,
you will get a large Burn icon to drag the files onto.
When you drag the first file onto the large Burn icon it will ask you to choose Audio or Data disk.
Once all your files have been selected and dragged to the Burn icon, you CLICK on the bar at the bottom which says 'Click Here to Continue'.
This returns the Action Window back to it's 'normal' display, but brings you to the burn window where you can see your chosen files (at the top), how much disk space they will use (at the bottom), and a large BURN button on the bottom left.
If all looks like what you want, click BURN
If you have done all that and THEN have a problem, what happens?
Please describe the situation in a bit more detail if you can.
