no comand prompts in sketch pad

Hi everyone,

I'm a new to 3D printing and just built a metal frame reprap i3 with a Mega 2560 board. Downloaded the software from this site (version 1.05r2), the tutorial says specifically not to instal the driver in the software for the USB but its the only driver there! When I run/open the blink program to load the driver and board I get a blue flashing LED, not orange, is there a problem with the board and tutorial?

I have tried to run/program the printer on two pc's, one runs Windows XP, the other XP Professional, same result on both.

I know the information has probably been posted somewhere (wrong word/phrase = wrong answers) but I have spent days lookingjavascript:void(0);

Thanks in advance Steve
