2 small bugs for the PMDG-800

1/ OAT temperature on the FMC: with parameters in Kgs, the entry of the field temperature in the FMC gives an "INVALID ENTRY"2/ the engines seem to stay in Reverse after start up, and setting back the FD to stop and ON again solves the problemHas anybody an idea? it is true that i have a lot of difficulties to set up my throttle for this plane... I choose the internal FS2004 in the PMDG menu, because FSUIPC setting gave me an impossibility to accelerate on the runway:-)philippe Strasbourg
