After multiple attempts at trying to purchase Qi I have been prompted with the same error message.

These are the steps I take when trying to purchase it:

Step 1:
Shop -> View all items


Step 2:
View all items -> Misc -> Qi


Step 3:
Qi -> Steam Logo under 1,000 Qi for 6 USD


Step 4:
Steam Logo under 1,000 Qi for 6 USD -> Order Created


Step 5:
Order Created -> Site Error



I have been prompted with this error message every time I have tried to purchase this AND any other amount of Qi. I don't know what I'm doing wrong.

it dosent look like you are doing anything wrong. Try buying it from the ingame shop for the steam version that might work

Solved
