theres only one problem i have to report at this time and it pertains to me only, if i run my current texture pack from 1.7.3 it runs smooth as butter but i dont see any of the new blocks' textures. if i go back to default pack, the lag is unbearable to the point where it takes me 5 minutes to pause the game.
In response to the actual blog instructions - problem. I got it all up-and-running O.K, but the game has frozen on the updating screen about 1/16 from finishing downloading. It says 'Done loading', but it's utterly frozen.
