I have Nero OEM 6.3, and when I make a 'multisession' data cd and try to add files later, it says I will loose everything if I want to add any. When I put the cd back in and try to add files, I get the message that even though my disc was recorded at multisession, if I want to add more files to it, the original files on the cd won't be able to be read. I've searched the info on the Nero site and I still can't get an answer. The strange thing is a few times Nero has let me add files to my discs (just a few random times it has worked right). I haven't changed any of the settings on Nero or anything so I don't understand why it's worked a couple times, and like 99% of the time I get the 'you will loose your original files if you add' message. If anyone can give me any help I would really appreciate it, thanks.
