After reading loads of solutions on various forums, and trying them, i STILL cannot get bf3 to run again....
IE - states only 32 bit is supported, and mine is 64 bit.
Chrome - states you need to launch Origin (Origin is already launched). Tried turning off 'plugin free' mode, but when I uncheck it and click save, it checks itself again so its impossible to uncheck it.
Fire Fox - states 'incompatible browser - you need to use IE or firefox', even though i *was* using Firefox.... Tried turning off plugin free mode, same problem as Chrome.
