messiah 2 installed, need help!

[dude2]

Hey,

I have just got my PS2 back from a modchip supplier who has put in a messiah 2 chip. I have got it back and when you put in a dvd it gives off a whirling sound... i dont think the disk tray it locked down properly. To stop the whirling sound you have to apply force on the top of the disk tray cover bit. How can i solve this with no more screws? Also when i put in a dvd movie (obviously as i say i have to apply force for it to run properly) it comes up as a playstation 2 disc and when you enter it, the screen goes black for a few seconds then returns to the slect a disk / memory card screen. what can i do!!!!

ahhhh

Thanks

Jonny
