Copying DF 2 (Someone please help)

[Viper187]

When i try to copy this game, i use Nero burn 5.0 (full version) and when it gets all the way to the end of the copy where it spits the disk out after it is complete, it throws and error that says "invalid field in command". What does this mean? What am i doing wrong? I have tried to copy this game about 4 times now and i am using 700mb cdr's as well so i know it will fit. Any suggestions on what i am doing wrong?
