Star Wars Battlefront 2 can't use my mouse

I am playing on PC and just installed the game after reinstalling my windows and i can't see or use my mouse in the game. First when it reached playable status i started the game but didn't see my mouse so i assumed i must donwload everything but when i downloaded everything it was the same. Then i checked the game files - same result so i decided to reinstall my game to see if its gonna be fixed - it was not so someone please help because i can't play the game for as long as i have this problem ...
