Help!

I was flying a few minutes ago and noticed something weird...every 3-4 seconds, the plane would put on full throttle, full right rudder, and dive to the ground!

I thought it was the plane at first, so I tried another one, but it happened again!

So now I thought it was the stick....So I went to calibrate the X45 and sure enough, full right rudder, full throttle, and random stick movements were occuring every few seconds.

What can I do to stop this? I've tried rebooting the comp, unplugging the X45 and plugging it back in, I checked Saitek's website, all with no avail.

What should I do?

All help appreciated!
