greetings, I recently purchased the hot start challenger 650 a couple weeks ago, and i've been having one small issue with it. when I use the FBO and set up for fuel, GPU time to depart, etc the time only lets me change between 1300z and 1400z. unable to change to another time, and i'm always waiting over 2000 seconds for passenger, GPU all that to hook up. well GPU maybe 100+seconds before it hooks up to the plane. also in the FBO ground handling, when I sign, it only signs for one date of March 22. any tips or help to resolve and fix this would be appreciated.
