Instagram feed not full width

Hello,

I hope someone can help me… I have a problem in which the plugin does not stretch 100% across the screen. I have tried a lot of things, and it is at width:100%; it may be a problem with my theme, I am not sure. Can someone have a look and give me some advice? the site http://www.pinballnet.com password: Tigers
