Thanks for the answers.
Btw, i play this game full screen (1920x1080) with win7 x64. I start the game and just before i'm entering the hardcore-mode, i use alt-tab and activate this tool and switch back again to the menu. I enter the hardcore-mode and have some fun with other players.
When I download it, it shows up as attachment.php I go to open it but I guess I don't have what it takes to may it possible what should I open it with and do I need a injector? Thank you for your help..
Rename it from "attachment.php" to "attachment.rar", 7zip work great and is free...
