(Help me please !!) I am a studio one3 professional user (melodyne problem.)

Hello. Please understand that I am not good at English.

I am using genuine sudio one3. I recently formatted my computer

I want to activate Melodyne after reinstalling.

(Your license options

Welcome. The status of Melodyne on this computer is:

Melodyne 4 essential Version 4.1.1 has been installed but no activation could be found.)

I get this message. Why is this happening? I am a genuine user and have used Melodyne freely

One more thing is that I logged into the celemony homepage

The serial number is different. Please resolve this quickly. I have to work, but I can not.
