DJI Naza M Lite Going Crazy

[f550fan]

I have a F550 hexacopter that i used to fly just fine with a kk2, just put in the naza lite with gps and it goes nuts. I have reset and calibrated everything and as soon as i get all 6 satellites and arm the machine, it shoots in to the sky spinning and moving every direction possible. So then i try and flick it into failsafe mode and it goes but doesnt land it continues to go ape. What can I do to fix it? Anyone else had this issue? I fly with a Dx6i
