Cannot play Blu-ray disc in HP hdx9350

[hamilton32]

I bought a blu ray disc (National Treausure 2) to play on my brand new laptop with its nice built in blue ray player.
It did not work at first and found out in the manual how to change the setting.
I found my country (Denmark) and it was set automatically to region 2 after asking my country.
Great I thought.
Tried it again and got the same message that the disc cannot play because of the region setting on the player.
I bought the disc here in Denmark and therefore it must be region 2.

Anyone know how to help me?

Also I must add I know very very little about the computers so please explain in detail.
