Thanks for the quick reply. I tried that URL as the first parameter above, and just the part without the https:// for the second parameter, but still no luck.
Now, even when I just go to the admin page for the cart, I get a 404 error: it is looking for: https://server119.tchmachines.com/crestore/admin/login.php (crestore is the directory I created in my domain for the estore, but it probably doesn't exist in this path).
Perhaps you can suggest what to do for all 3 parameters.
