Blank CD errors

I downloaded the trial version and have been testing it but whenever it asks for a blank cd and i put one in, it will just stay on that screen and not move on even when it says that a blank cd is in my drive. Ive searched a bit on google and the site a little but havnt found anything so far. any help would be appreciated.

Please post a complete system report from within Alcohol and the steps you used to make the image.
