Ever since I got my CD burner I've had no problem burning CDs from stuff off my computer, other CDs, anything. No problems. All of a sudden now, I keep getting a message saying that it can't burn, and it tells me to check for scratches or try a different brand of CD. I know it isn't scratches because I tried about a dozen of the CDs. And it shouldn't be the brand, because up until now I've been burning CDs from the same STACK with no problems. Why it suddenly be preventing me from burning onto these CDs?
