more information, such as the following the forum tip which was in red right above where you put your subject in, we can only guess. Did it EVER work? What year is the NIS program. What is your operating system? What are your computer specs? Have to done virus/spyware/adware scans? I will copy and paste the forum tip for you again.
Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.
