People have this problem if they skipped installing the DirectX 9.0c End User Runtime when they installed the NXT client or failed to install it for some other reason. You can install the DirectX 9.0c End User Runtime separately. Below is the URL to the full download of the DirectX 9.0c End-User Runtime:
Create a new folder on the desktop. Run the program you downloaded to extract the files to the new folder you made. After extracting the files go in to the new folder and run DXSETUP. After DXSETUP is finished you can delete the new folder from the desktop. Restart your computer then try to run the NXT client again.
Let us know if that helps or not.
