106 not reading Playstation 2 Games?

I’ve had my 106D for nearly 2 years and all of the sudden it won’t read my new ps2 games, when i put them in, it keeps reading but the pc locks up entierly, however the drive reads all of backups perfectly and its only my legimate copies that it locks up on. it reads all other dvd media perfectly, movies, backups everything, just won’t read new legimate ps2 games.

does anyone know why this would happen and a possible solution?
i’m running XP SP2 and my firmware is 1.08.
