Take another look at the video driver version.
OpenGL driver information:
Vendor: ATI Technologies Inc.
Renderer: ASUS EAH6850 Series
Version: 4.0.10243 Compatibility Profile Context
blockland shows your are (were?) running version 4.0.10243, but the current ATI drivers are at 12.x, so your WAY behind the times.
re-check your console.log to make sure blockland shows the same version as you downloaded. If not, then your driver update didnt work right.
