Upgrade Solo 3 to Performer


#1

Purchased Cantabile years ago, never used it, just wanted to have it handy and years later here I am.

I paid for the yearly fee (new to me) just to get things going then realized the 39 bucks wouldn’t get me Performer 3 (I have Solo 3).
Can I just upgrade again today and pay the difference?

Do not wish to click PayPal again if there’s a link that realizes what a bozo I am and just adjusts the payment?

Thanks
