Steam says, i don´t own the Deluxe Edition - but i do. I can drive all cars, but in steam, some cars (of S1 and S2) are not listed in the library. So technically, i own the deluxe edition, but steam thinks, i don´t do. I ordered the Disc-Version of the Deluxe Edition. Does anybody have a hint for me? Does anybody know, who i can contact? I´m asking, because i don´t get Discounts for owning S1 and S2 - and probably, i will not get the Colin McRae Pack for free. Greetings from Germany.
