you don't need service pack 3....some people just don't know what to do.....
if you have all the requirements all you need to do is get the dll of FGTim (1/31/2011) and put it on a new folder, then get the injector of xflick (1/30/2011) and put it on the same folder as the dll, then rename the injector with the same name as the dll.....
i encounter many warrock user with this issue...they have dll from FGtim and injector from xflick but with different filename...
