Hey there!
Courses can take between 24-48 hours to open upon the completion of the previous course. I would recommend giving it some time before trying to continue on. If your courses still don't open after 24-48 hours, you can contact Student Care and they should be able to recognize if there is anything wrong with your account. From there they will assist you in fixing whatever issue that may be present. You can contact Student CARE Forum by email, in the community, or over the phone at 1(888)427-1000 during regular business hours.
I am sorry for any sort of inconvenience. Best of wishes!
