Im having a problem with Tony Hawk 2 - can anyone tell me whats happening

Hey, i have a SELF BOOTING back copy of Tony Hawk 2 that i ordered from a website and im trying to make a copy of it. I am using DiscJuggler, when i go to make the copy -i select "Make copy from same CD Recorder" then hit start. the error i get is: It says Caching Track 1 of 2 then about 3 min into it , it says:L-EC or CIRC unrecovered read error and automatically stops. What am i doing wrong and what can i change for it to work
