The PC version of this game is the second game ever in my experience to suffer from one of the most annoying bugs to troubleshoot. First game was Warhammer Online.
I live in Finland, but use English language on all my software, including my Windows 7. If, however, I choose to set the regional setting (dates times etc.) to 'Finnish' all the names of dates and months appear in Finnish in my otherwise all English operating system. I hate that. If I choose 'English' for my regional settings, all that is correct, but things like dates and times in numeral format are displayed wrong (12h clock, mm/dd/yyyy) and I hate that. Also things like currency format ($1,000 versus 1 000 ) get fucked up. My solution was to set it to 'English' but then manually edit them to reflect how they are supposed to be in Finland. Works fine all everything but Warhammer Online (played it for a week, so no issue) and Dead Island.
What is the bug, you ask? Interface buttons like the ones in all menus (Start, Load, Options...) don't show up at all and the fucking mouse doesn't work. At all.
Yay!
