Edit : Or wait i uploaded it here ^-^
[Only registered and activated users can see links. Click Here To Register...] you can scan it first with Virus Total if you got any doubts :P
First you run the game, then run the WApro ( Vista or Win7 run as Administrator ), in the "Window name" you type "twelvesky2"
and in the "Process Name" you type "TwelveSky2" (make sure you use capital "T" and "S"), tick on the "Continuous scan" then click on "Make it happen" . A window will pop, your game will be inside, then you can reopen the launcher again and again, and you can minimize the game INSIDE the WApro window.
Hope this tut helps ^^
