Ah, I see. I always create a txt file with the order number and place it in the same location as the program install files. I know I’ll lose it on paper or in an email. If I lose the txt file then that means I’ve lost the install files as well and deserve to repurchase the program.

"Take the cylinder out of my kidneys,
The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
