If you are seeing the error "Failed to initialize graphics. You may need to update your graphic drivers" then that indicates a problem with how Chrome is interacting with your graphics card. (This was previously the "stuck at 99% loading" issue.) Chrome Native Client will not work with certain hardware and software combinations.
The first thing to try is to make sure you are running the latest video drivers for your hardware.
