Did this happen suddenly or did you do something recently with the phone?

when someone calls my phone, it no longer rings or vibrates, but only lights up. I thought it may be an audio problem so i went to my gallery and played some ringtones but when i hit open it replied :unable to open file." I dont know if these problems are related, but its hard to answer my phone when it doesn't ring or vibrate in my pocket. This is my business phone so I really need help. Thanks.
