Problems during take off with PMDG 737TNG

Hi guys.I have just installed the patch and was planing a Flight from EKCh-EIDW this morning.Everything went fine until take-off, I lined up and made the final check, flaps 5, autobrakes RTO and ready to go. A/T armed and N1 activated, the plane spools up to take-off trust and when passing 110-120 the throttle returns in idle position and the autobrakes activates. I tried this 2 times and the 3 time I tried without Autobrakes armed. The same happens, when passing 110-120 the throttle return to idle.I have tried to calibrate my control and instead of using N1, I have tried the TOGA, but the same result.Can somebody please help, so I can fly this lovely bird ?.SincerlyPeter
