Hmm, I updated my Nero from their site and didn't get that issue. Have you ever done that?
After I installed the XP SP2 on my computer, I noticed that every time I started up Nero I get a window that pops up saying that Nero has a known compatibility issue with this version of windows. I can select 'continue' and it still works, however at a much slower speed than my drive is capable of.
Anyone have this problem or know how to fix it?
