I just got a new hard drive, and I tried installing worms right away. I installed Worms Armageddon, rebooted my computer, and went through the whole process. However, when I tried to load the game, an Application Error came up saying, "The instruction at '0x01c528b0' referenced memory at '0x01ca4d00.' The memory could not be 'read'. Click on OK to terminate the program." Not only that, but then I tried to download WWP, and nearly the same thing happened. This time, the Error didn't come up; the screen just turns black for a couple seconds and then goes back to the desktop. It won't even load. Does anybody know what's wrong?
