Actually, I don't really think this is SQEX Dev Team's fault... This error happened to me 10 times only this night. It's so annoying I got pissed off and reformated my PC in order to clean everything up and only install the drivers and Final Fantasy XIV to play. The error happened again other three times. So I went to do a research... In many programming forums I saw that Microsoft is blaming the game developers for this Runtime error, but the users are experiencing the same thing with Internet Explorer, Mass Effect 3, Star Wars: Battlefront, Diablo III, Final Fantasy XIV, Star Wars: Jedi Academy; and many many other softwares, on Windows XP, Vista and 7. I guess there are too many developers involved in this to be their fault and not Microsoft's :/
I read many posts telling us to try to open the game from the setup folder, and Open as Administrator. For some games that works, for others, that doesn't.
