Combat arms help needed

hi,
i cant see or use my gun when ingame in combat arms
everything else is fine but when it comes to seeing my gun or shooting or reloading it doesnt work
i can still use my knife and nades but not pistols or main guns,
also i can use the sniper rifle (most powerful one) but cant use any other guns. help please

Try redownloading CA and then try using a different gun. If it doesn't work then let me know.
