errors, errors, errors, damn that discjuggler sucks; help me pleeeeeezzz !!

I have burned about 65 games using DJ, but I have had some errors a few times. Today I downloaded 2 games : The Grinch and Sno Cross. I extracted everything and injected bla, bla, bla, but when I tried to burn the images they gave me errors : The Grinch had an illegal field in command descriptor block error and sno cross had an illegal parameter field error. I have had this before with sega extreme sports and super runabout SF edition. Can someone pleae tell me what to do about it, cause it's driving me mad !!!
