What color was the box? If you get an amber "AST OFF" box it means the autothrottle is not available. A common reason for that would be that you have pushed the overboost bar by mistake. This results in engaging the ALT FADEC mode and disengages the ATS (for the PW engines models). In this case you will also get amber "FADEC ALTN" alerts on the EAD. If this happens you should reset the overboost bar (click on in) then on the overhead panel press the three FADEC guarded switches.
