I just recently purchased a flip top case and the two swap magic v3.3 discs and i instaled the flip top case. But when i played a burned backup the discs did not work. I burned the game in the DVD-r format and folowed instructions, but it didnt work. My friend had swao magic v2.0 and worked. Is there something wrong with the discs or did i do something wrowng. I need help.
