norton 2012 identity safe locks IE8 when I try and log in Windows xp sp3

Having real problems here, browser loads fine, then I try and log into identity safe by clicking on the log in under lock symbol and browser just locks completely! Have tied to log in via norton and this just locks norton up as well, meaning reboot.

If I don’t log in to identity safe then everything is fine.

Have done the uninstall and reinstall but the same thing happens.

Have applied all windows updates.

Have been trying to fix this for a week so any help would really be appreciated. Thanks.
