Yet another DJ 2 problem... Please help.

Okay, i have a Smart and Friendly CD-R, and I'm trying to burn ferarri 355 and about 10% or so it spits out the cd and asks for the second cd. The file is about 720 megs, and I think it's trying to put 20 megs on the first disk then it wants me to insert another disk for the rest... Anyone else experience something like this and know a solution? Thanks in advance.
