Problem Backing up Marvel VS Capcom

Hello,
I borrowed a Marvel VS Capcom from my friend so i could make a back up. I've used Discjuggle 2.X to burn the game. The burn goes without a problem but when i put it into DC, nothing happens. Whats going on?
Ive burned other games successfully but what is the problem. I have "ignore error and over burn cd" checked. I have a Yamaha 4X4X16 SCSI CD-RW. Please help.

Thank you
