Can't get my copter to arm

i got the F450 GPS Drone Quadcopter Ready-To-Fly off ebay…i have followed the instructions even used the wizard all seems fine apart from its dead when it comes to arming it i move the right stick to the right for 5 sec and nothing. yet there is a connection with the copter as i am getting the battery life of my copter on the screen. the gps light when finds signal stays lit and the red light still flashes and thats the only sign of life i get apart from a small twich of the props when i plug in the battery and some beeps on my controller.

so i am about to give up and think i have brought a dud
