Mobileme problem

Mobileme will not register my Macbook pro will. The spinner keeps going round but that's it.

I left like that for over 2 hours yesterday with no joy.

My iMac registered without a problem.

Apple don't know the answer to this does anyone here have any ideas?

Got it sorted after another call to Apple.

It was an error in the keychain, it was trying to use the wrong login details.
