Upgrade another computer to Tumult Hype Professional

I purchased hype pro for my macbook pro.
Today i bought new imac.
If i install hype on my imac with my account.
Then upgrade to hype pro.
It ask me to upgrade.
Do i need to pay again to upgrade?
I really need to know.

If you have upgraded once already you do not to re pay, in your case you should be able to:

go to Upgrade > Restore purchases to re-enable Pro.

thank you so much.
It works.
thanks again.
