I just got swap magic a few days ago and has worked great. I've burnt 3 games and successfully ran them. I went to my cousin's house and played with my swap magic on their ps2. Now it doesn't work on my ps2 anymore. When I put in my backups it says "Not a Valid PS2 Disc" and makes a small clicking noise when trying to read it. Can someone please help me out. Thx. My original games and swap magic work fine.
