noob here. i'm assuming you're trying download image via command line? i'm sure aware can here if continue have problems: http://www.raspberrypi.org/downloads/
also, if installed, i'd appreciate knowing problems encounter during initial boot. have attempted boot distro on pi b+ weird looping display problem no control of input stop or interact solution. pointers appreciated.
