After Installing Orbit Downloader with Grab Pro...I can't able to access sites on both firefox and IE
Yes same problem with me . So i Disable the GRAB PRO addons in internet explorer 8 to do this go to Tools->Manage Addons->right click on GRAB PRO and disable it. and internet start working
Does that mean, you are unable to access internet?
If yes, have you tried un-installing Orbit and tried? Orbit doesn't have power to disrupt ur internet experience, so there is some other reason for net problem...
