Actually, I wrote down exactly what the screen error was on Nero this time. I was a little mistaken when I wrote the first time. Rather, this is what the error screen says in Nero when I try to burn the image (.nrg):
"The Disc must be written in 'track-at-once' mode ('disc-at-once' mode not supported or not able to write such a disc). Unfortunately, your image has a special format which more than likely can only be written correctly with 'disc-at-once' option enabled. But you may PROCEED AT YOUR OWN RISK. Do you want to continue burning?"
That quote is exactly what Nero says to me when I try to burn this particular image. I've gotten a different image of the same thing from my friend's house and it says the exact same thing.
Any suggestions? Do I need to reinstall Nero (because I actually upgraded from 4.XXX to 220.127.116.11)? Does it have remnants of the old Nero in the registry? I need some expert advice....
