I downloaded a file in .ISO form and I am trying to burn it to a CD. I get this message and can't understand it: "The entered block size does not correspond to the image length. The block size may be wrong. Do you want to correct the value or ignore the problem?" Then it gives me chose buttons to ignore or correct. I can't correct it because I don't know what to do. When I ignored it, it burned a CD that is not accesssible. So I just wasted a disc. I'm using Nero express, with CD-R's. Can anyone help me with this problem? What can I do?
