Messiah 2 problems

[Dead_meat1200]

I just recently purchased a PS2 with Messiah 2 installed, but it doesn't work right. It doesn't boot PSX games (original, import or backup). Whenever I try to start it I just get the message to insert a Playstation or Playstation 2 game.


PS2 games it does boot (both original and backup) but quite often they crash on the loading screen.

It doesn't boot anything after resetting (same message as with PSX games). I always have to turn of the entire PS2 when starting up a new game.

What can I do about this problem? The store that modded this PS2 doesn't exist anymore (I got it 2nd handed). Any help would really be appreciated.
