Hello eduunn, Plz do go to the home page IK mentioned. Also a little more info plz. I had the same problem when I swapped drivers on my video card. Did you already update your drivers for you TNT 2 and sound card from CL?
Let us know how things worked out. If you still have the problem, I'll send you a a$$ load of URL's that discuss this problem.
