if you cant burn any CD, then there are few steps you can try:
1. click the CD drive with the right button of your mouse, then go to properties.
2. see if you have record option on it. ( if not, then i dont know)
3. click on the record option.
4. check the textbox of "enable to burn CD". ( i think)
if those steps work, then thats great.
if they dont, i sorry, i dont know any other ways.
