Buy sript fail

Hello! I just buy script from this link

I pay with my card, money goes out but in My Purchased section don’t have this product!
What have to do now?

have a look at documentation here.
i just saw that your script isnt up to date, its from 2015, but i don’t think that’ll cause your problem.

but if you search it in the asset store inside of unity you should be able to press import, its the button where you pressed buy
