Language? Ignore the rating: Cannot rate...yet

It says the language is both English and Swedish but everything is in Swedish and the splash screen is asking me to register or something but I cannot understand Swedish so I cant get the program to start beyong the starting splash screen window. How do I change the language to English? I cant really rate this yet because I cant start it and if I could, I couldnt understand it if it displays only in Swedish. This review is forcing me to rate it before I submit it so I am giving it middle 3 star.
