After updating the Nintex Workflow license file, some workflow actions might no longer appear as expected.
Verify that the appropriate license was renewed. Some actions require an Enterprise license. If renewed at the Standard level, all of the Enterprise actions will disappear from the workflow designer. To gain access to these actions again, import an Enterprise license back into Central Administration.
Actions such as: Query SharePoint User Profiles, Add/Remove User from AD Group and Provision User on Exchange require an Enterprise license.
