Phantom 1 won't arm motors nor take off!

[mike8867]

Ok so my phantom 1 used to fly just fine, no crashes, no drops, and randomly one day didn't want to take off. It's connected to the remote and after I calibrate it and all, when I go to arm motors it just blinks red and green. And when I try and arm motors it rapid blinks green and then back to red and green. I have tried hooking it to assistant 2, and the phantom assistant one and the programs just won't recognize the phantom being connected. Please help. I'm lost. Thanks
