Another purchase, another problem. I bought the Ninja Assult with the Gcon2 bundle today only to discover that the gun dosen't want to be calibirated. In the menu when the gun's connected you can see the cursor flying about in random places. When i reach into the calibration menu, i point the gun at the tv, the cross appears when i suppose to shoot to calibrate it but it just dosen't want to shoot! I even tried on a diffrent tv but still the same problem. Is it some gun problem which can be fixed or should i go back to the shop and maybe get a replacement?
