First I have to mention that I am not sure if this is right forum, so if not please move it.

Now here is what is going on. I just installed software for Pinnacle's PCTV Deluxe and after I rebooted computer, small window from Nero came up with this error

It has been corrected.

You must reboot your computer in order the changes are effective.

Until then, you may not be able to access your CD-ROM drives.
This happened on my Laptop with DVD-ROM in it and now I just realyzed that same error pop-up on my home machine with WinXPHome too. Since then I was having problems with home PC DVD-ROM. Somtimes it refused to read CD.

So does anybody know what it means and how can it affect reading of disks and how to fix it or how to check if it is correct ?
