RudyLis: Most hilarous part: Steam offers those updates. Though seeing those "upgrades" actually makes me willing to ignore them.

bossonova: Agreed and for a game of this caliber its better to get it off of gog for sure

tmcd: You have to contact support, then instead of "games support" choose "contact us", then "My orders, payment and downloading games", on the tab "problem type", choose preorder cancelation and choose the approproiate order or "not applicable" if appropriate. Lastly explain the situation and send the ticket. It takes about a day for them to answer(it was with me). And if it goes like with me they will ask you to give your money as store credit, wich you will use to repurchase the apropriate edition (royal edition). You will of course have to pay the difference. That's it! Best of luck!
