If you have paid by paypal and your Opt2Learn and paypal email addresses are different, you will need to add your paypal email address to your Opt2learn account in order for your paypal purchases to show.
You can do that quickly and easily by doing the following:
As you can see below, all you need to do is log into your Opt2Learn account and click on the Add my paypal email button (highlighed) and add your paypal email address you used to make the purchase.
Opt2Learn doesn't get access to any of your paypal information, or your paypal account, it simply allows the system to assign your paypal purchase to your Opt2Learn account.
Once done, your course should immediately appear in Your Courses.
If it doesn't, please raise a help desk ticket and we will have a look into it for you
