In order to use the LSAC website or LSACD products on a computer with XP Service Pack 2, you have to add “*.lsac.org” (without the quotes, and that’s an asterisk (SHIFT-8) at the beginning) to your “Trusted Sites” list.
In Internet Explorer, click on "Tools", then "Internet Options". Then choose the “Security” tab. Then click on the green check mark for "Trusted Sites", and then click on the “Sites” button.
In the new window, uncheck the box at the bottom, then enter *.lsac.org in the field at the top and click the “Add” button.
Then click "OK", then "OK" again. Close your browser window, then open it back up and log into Online Services again.
The website and applications should work properly from now on as long as you leave *.lsac.org on your Trusted Sites list.
