After my refund I'd like to test rf2 again. So, I bought the rfactor license but after I confirm the payment I get the following error message: Why? The first time I bought rf2 I did it exactly the same way.
You requested a refund, and this will have caused your issues I guess. It SHOULD work fine though, so I would contact support and see if they can look at your account, if you didn't do it already.
