Windows/Nero quit recognizing DVD Burner

[Ahriman]

Here's what happened. One day I was burning a DVD being happy and all, and then all of a sudden Nero quit recognizing the DVD burner. I've tried to reinstall Nero and tried reinstalling the DVD Burner. If anyone has any suggestions to help me with this problem, please let me know. Thanks
