hi.. just wondering, have any of you experience this:

Last nite i couldnt sleep well so i i turn on my tube and start listening to the musics on my tube.. after playing it for almost 2 hours, the music stop and i got this message - DISC ERROR, FAILURE IN WRITING FILES or something like that lah.. So i switch off and on again everything back to normal and then i happened the second time.. then i used the original theme and i works normally now.. so is my memory card corrupted or is it just the theme im using?

Why i cant get Marble Maze to work on my tube??? I try to open the game then i goes to black screen for 1 sec then back to the menu screen.. somebody pls help me thanx..
