Padshop 2 and padshop pro on cubase 9 pro

Hi I have padshop pro and cubase pro 9

I tried to install padshop pro 2

is this a free upgrade for padshop pro users?

Now i can’t use it it says i need to register it

if i can’t register or use padshop 2 i need to remove it

how can i do that and go back to pashop pro now.

Thanks MK
