Email scanning in NIS08 on Windows Vista

I m not able to enable the Incoming and Outgoing emails scanning on my system. It was working previously, i was forced to uninstall NIS08 and when I re-installed it, its not allowing me to enable these options.

 

Its giving an error like ' The options interface couldnt be initialized. One or more of the Symantac services may not be running. Please restart your computer and try again.'

 

I tried  this 2-3 times but its not working.

 

Someone pls help me in enabling the same.

 

 

Thanks in Advance
