NERO 6.6.0.5 problem

Im using a bundled version of Nero(6.6.0.5) and when I add files to make a cd Nero is putting the wrong time on them so when im finished the files are ready to put on a blank disc are too long in total to fit on a blank disc??
So how can I solve this problem please!!Ive altered the overburn to 90 mins and just got some 90 min disc but because of Nero they wont in total fit on there either!!

If it’s an Audio CD you’re trying to create try Burrrn (www.burrrn.net) .
