Hi Im Dan.
new to computing/gaming but already about to throw laptop out the window.

First, I think I am xubuntu.
Bought Tom Clancy, Rainbow six 3..Raven Shield.
Put disc in slot..Get a message saying 'mounted' and a disc icon on desktop.

Laptop automatically jumps to some media page that says file manager with a dozen icons with little locks on them and thats it..cant get any further.
I just want to put a disc in and play a game..is it too much to ask? Please help.

Thank you for your help and considerations to my now very fragile mental state.
