IPhone won't connect with iTunes?

Hi when i went to put some music on my iphone 3gs today i opened itunes like normal and connected my phone but it opened a window called autoplay and the usual iphone section no longer appears, i've tried all sorts to solve this but nothing seems to work any suggestions?

Added (1). Thanks for the answer sulley but i have tried this and it doesn't do anything nothing it seems the computer thinks it is a camera as the logo is a little camera if that helps?

Connect your iphone to computer when auto play appears close it by clicking on top right corner
then open iTunes you will see your phone there.
