Unable to register my Pickcel digital signage screen, getting an error as Invalid registration code

I am unable to register my screen; getting an error as "Invalid registration code!"

If you encounter the above mentioned error, please perform the following checks:

1. Ensure that the registration code is entered with the correct letter case, matching the code displayed on the screen precisely.
2. Verify that the server name on the registration screen matches the server you are attempting to log into. Both should correspond accurately.
