Sometimes i can´t gear up. Green and red lamps are shining. I tried to reset the service time. Where is the problem and how can i solve it.

Using the 'G' key on your keyboard or something else?When you're posting a question about an error, it's always a good idea to tell us exactly what happened:-Using any hardware?-Using FSUIPC?-Using ASE?-Was the sky purple?-Did you click on the gear handle?-Was there a leprechaun at the end of the rainbow?...and most importantly: Are you loading the plane with a PMDG Panel State through the FMC?
