I have just re-downloaded minecraft after deleting it from my CPU. Once i started it up and everything loaded. I can see through the ground, and certain blocks far away are black. I have updated my Graphics chip(since i am running on a notebook PC) To the most recent version. I have a ATI Mobility Radeon 4200 series. (4250 HD to be exact.) with 8 gb of ram. AMD Turion II dual core processor. Could really use some help with this asap!
Everything is black or invisible.
