Cracked Screen and Unresponsive to touch

I have a Chromo Inc Tablet, I recently got for my birthday.. I put my tablet in my purse and i carried my purse around with me all day.. but i did not have anything that could crack the screen in my purse, when i got home i gently grabbed my tablet and the screen is partially cracked and unresponsive to touch, only on the very bottom of the screen it will respond to touch but the top and the middle of the screen is unresponsive..I've only had that tablet for 1-2 months.. How do i fix this? do i have to get a new screen? Im worried about loosing my data, I have IMPORTANT data in the device, i have things in that device that are important and i cannot get past the security screen, Please help.. Thank you SOO much!
