When I try to open norton 360 an error message appears

Whenever I try to open Norton 360 through my taskbar, or through the start menu, windows comes up with a message saying"Norton 360 has stopped working, Windows is checking for a solution to the problem".

From the tray icons, I can left click the Norton icon, which brings up a menu, allowing me to run quickscan, live update, backup now and more. if I click on any of these it takes me to the relevant page and completes the task. However, if I try to open the Norton "homepage" it comes up with the same error message. If I run Get Support, it checks my instalation etc. without any problems, directing me to come here.

This problem has been ongoing for a few months at least. Sometimes it does work, but in all I am disappointed with teh service offered by Norton. Does anyone know anything about why this is happening, and how I could stop it?
