Confirmation e-mail doesn't contain order ID -> I cannot verify my website purchase

[SliM]

Hi!

I bought Poweramp Unlocker many years ago and I want to activate the app, but the Unlocker.apk says my phone doesn't compatible with it.

I tried to use the purchase restore method, but I saw that I need a order ID for it what I cannot have.

I have the confirmation e-mail, but it doesn't contain order ID.

Attached the confirmation e-mail.

Can you help me?
