PSP Spiderman2 UMD cannot be read
 

I just got my Spiderman2 UMD this morning, after putting it in the drive I get a lot of whirring noises & then a message that the disc cannot be read. Does anyone know of the replacement procedure?

Update
 

I was just on the phone with PSP customer support. While I was waiting, I looked carefully at the disk surface & saw a tiny chip of plastic that was stuck there by static. After a lot of shaking around, I've got the chip out & now everything works fine.
