Pax Dei Launcher Error 0401 - 1460

Question: What can I do about the following error in the Pax Dei website or in the Pax Dei Launcher?

• 0401-1460: You have reached purchase limit of the item: [ITEM]

Answer: This error may appear when you try to purchase an item or a bundle you already purchased once. Indeed, for now, you can only purchase one a Founder's Pack (but you can upgrade if your current level of Founder's Pack allows it).
