HELP! What went wrong? Getting errors in CDrecord...

[Excalibur007]

I've been using CDrecord to make my games selfboot, VGA compatible etc. So far, I finished 11 of them.
Yesterday, I started getting errors when trying to burn the 2nd session. Today, I can't even burn the 1st session without it messing up. I'm not wanting any more coasters until I find out how to solve this.
PLEASE HELP!

Here is what the message is saying in DOS when I try to burn the 1st session:

If anyone can help me get back up and running, I would REALLY appreciate it.

Thank you very much!
