hello, i have been using mods for a long time, and this problem only occured now. you see, i was hearing about minecraft 1.4.8, and like the idiot i am, i thought they realesed it, so i pressed force update and it started downloading something. when it was done, it still read 1.4.7. i decided not to get down, so i tried to play my mods. i opened magic launcher, put in minecraft forge, and mo creatures, GUI api, and custommobspawner. the mojang screen showed up, and after a while it black screened. of course, i thought it was mo creatures. i removed mo creatures and kept forge, aand pressed test, same thing happened. i tried wiping .minecraft and replacing it with my back up, same thing. iv'e tried everything, please help!
