Access failure in Nero 5.xx



I’m having trouble creating a compilation audio cd from multiple cd sources with Nero 5.xx in Win98. I insert the first disk, drag the tracks over from the browser window to the compilation window, eject, insert a new disk and get the message “access failure.” This is a new problem, I’ve been able to make compilations in the past. It’s not a hardware problem either, because I can compile tracks from multiple cds in TDK Digital Mixmaster. I did go to Nero’s website and re-read the instructions and I am doing it right. Any ideas on what’s going on? I am trying to update my Nero, but with dial-up it’s not easy to download 18 MB before being disconnected.
