I might be able to help. First create a new file drupalcron.sh. Open in a text editor and add the code in blue (change "myweb" to your site name):

#!/bin/sh
/usr/bin/lynx -dump -accept_all_cookies 'http://myweb.asu.edu/cron.php'

1. Upload drupalcron.sh to your \scripts directory. Note this is a top-level directory. Create it if necessary. It needd 755 permissions.
2. Sign into DirectAdmin.
3. Go to your account and click on the Files icon at the top of the page. Check the permissions on the \scripts directory. Change to 755 if necessary.
4. Click on the Home icon at the top of the page. At the bottom of the home page you should see an Advanced Features section. Click on the Cronjobs link.
5. Enter the minutes, hours, months, week, etc., and the path to your drupalcron.sh file you just uploaded. For example: Enter "15,45" in the Minutes box and this line in the Command box:
   /home/usi/scripts/drupalcron.sh
6. Click the add button. Then go into Drupal. Under Administer\Logs\Status Report you can check the status of your cron job.

If you're using the ASU webhosting, you should be able to configure your cron jobs through DirectAdmin (the link is located at the bottom left under "Advanced Features" - it's a pretty simple GUI.
