Customer has migrated McAfee APS account, and login to McAfee Account is not possible. When customer goes to CCP > McAfee > Login to McAfee Account, the error is shown:
A System Error occurred. Please try again.
This issue is happening because the Staff Member and the Service User for this account have the same email so McAfee does not allow to have two assignments with the same email and the data is crossing. When the user tries to modify the contact information of the Service User, the APS send a call to McAfee in order to change the data but McAfee returns an error because this email is already registered with another CCID.

Try changing the user 'Email (to sign in)' back to old email address from control panel OR contact McAfee support directly in order to remove the user with this email because it does not exist in our system. Please also make sure that you are using the latest available version of McAfee APS package.
