Can anyone tell me why this is processing the receipt, but failing to load the character? Thanks.

local MPS = game:GetService("MarketplaceService")
local function processReceipt(receiptInfo)
	if receiptInfo.ProductId ==  961264618 then
	local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)	
		if not player then
			--player left game
			return Enum.ProductPurchaseDecision.NotProcessedYet
		end
	print(player.Name.." just bought "..receiptInfo.ProductId)
	player:LoadCharacter()
	return Enum.ProductPurchaseDecision.PurchaseGranted
	end
end

MPS.ProcessReceipt = processReceipt()
