I have a MSI 48x16x48 CD burner and I have used it in the past but not for about 4 months. I have burned pictures on CDs before succcesfully, but my latest attempts have been frustrating. No matter what I do, the comment keeps popping up "please insert disk" or words to that effect. I used to use it as a regular cd drive, but it won't even let me do that, no matter what disk I put in, it just keeps coming back with the same comment, "please insert disk". I am running NERO 5 burning program on it and my operating system is ME. Any suggestions?
