If you wish, you can restore your cookie settings to their original positions after you have finished using the course.

In the event that you are attempting to proceed to the next unit in the course and you are returned to the login screen or you receive a "page cannot be displayed" message, the problem might be caused by a failure along the electronic route leading from your computer's server to our server. Whatever the reason such an error occurs, it is possible that your browser might be caching the page containing the error. If this is the case, then it is a good idea to check your browser settings in the following manner to make sure the page does not continue to be cached:

If you are using Internet Explorer, select "Tools" from the drop-down menu at the top of the screen, then select "Internet Options." The "General" tab should be selected. In the section titled “Browsing History” or "Temporary Internet Files", select the "Settings" button. At the top of the "Settings" screen, under the section "Check for newer versions of stored pages," the radio button that is selected should be "Every visit to the page." Click "OK" and then "OK" again to exit.

In order to be certain these changes will take effect, you should close down your browser completely, re-open it, log in again and return to the last point accessed in the course. If you still experience errors, then the problem might be related to net congestion or some other phenomenon not covered in this section. If your problem is being caused by net congestion, you might want to wait until there is less traffic on the Internet before attempting to access the course again.
