Lost internet connection after installing NAV 2009

Hi, I have just installed the NAV 2009 and my internet went bust ! no more connection using any browser !

But there is connection for my pop email though... what happened ?

 

I was glad I was just trying out the free trial, and if this is the real purchase, I would have regretted if it really going to cause these sort of problems...

 

Anyone can kindly advise how to get around this ? except me having to uninstall the NAV 2009 ...

 

Thanks !
