Hi there, i had exactly the same problem. So I went to
http://support.intel.com/support/gra.../CS-007910.htm
and followed their instructions. Success! Everything works fine now.
Just type the error message you get from LOTR into google and you should find a solution if that still doesnt work.
hope that helps, and that im not too late and you havent sold it or smashed your computer up...
happy gaming
