All of a sudden Nero began throwing up a message telling me that my CD-R disc is unwritable, that it's the wrong media type, that I need to use CD-RW. I have never used a CD-RW disc and have never encountered this problem with Nero before. Nothing has changed as far as hardware or software. I have scoured Nero's settings in hopes of resolving the problem but cannot find anything that will do the trick. What gives? Anyone out there have any suggestions?
