I downloaded the microsoft security patch as soon as it came available and I don't have the msblast.exe running. So I presumed I'm in the clear from the latest worm. BUT, all of sudden Nero express cannot burn to CD-R but it can to DVD. It says the media is not suitable no matter what kind of disc (data, mp3, vcd etc) I try to create. I've tried numerous CD-R / RW discs, but it makes no difference. My drive is Pio 106. What's even wierder is that my brother has just encountered EXACTLY the same problem on his machine with a different drive. I think something's going on. Anyone any clues?
