No Country For Old Men problem/not region free?

[pandys-box]

Upon receiving my No Country For Old Men Blu-ray today I popped it in my player eagerly and was presented with an on-screen message 'Copyright Violation' - this is an original disc purchased from Movietyme. At first I thought maybe the disc isn't really region free as it has been stated everywhere but then on close inspection of the disc surface there appears to be a thumb-sized 'wet looking- area on the outer edge of the disc, and a small raised bump in this area. Has anybody had a similar problem with a Blu-ray or can lend any assistance please.
