Please check that you are using the same email address as your previous class.
Each email address you use (even if there is only a slight variation), counts as a new account. For example, email@example.com and firstname.lastname@example.org are two accounts.
Please double check what email you used originally. Then, if it is different, please contact your course provider and ask them to resend your class invite to your preferred account. This will make sure all of your Wet Ink classes are in one account.
Make sure to do this before you join the class and start submitting work - as work from separate accounts cannot be merged together.
