PS2 Help Would Be Kind...

Well, I just got my kingdom hearts 2 FM+ game, and i'm overjoyed to see it. I've been waiting for it for 2 and a half weeks, but I didn't care. When I used Swapmagic and then put in the disc...it made very loud clicks and claks.

When I opened the PS2, I noticed the laser was waaaaay to far back to read. Either that, or my PS2 was jammed somehow. It can still read some disks, but not my Star wars battlefront games and Kh2FM+ game...

Please help me! I've been waiting for this, and I don't want it to jam up! I really hope someone helps me...

EDIT: My brother fixed that, but know I can't go with the story. I freeze up when I'm at the intro, and I can get nowhere...

...This hurts badly...
