I recently purchased the PMDG 737NGXu and have it installed in P3D V5, I also installed the correct version of FS2Crew for the same. When I go thru the startup process, I run into a problem before takeoff. The hydraulics are not working properly. On the lower overhead panel, the Low Pressure light is on for Flt Control A and the Feel Diff Pressure light is also lit up. My rudder pedals don't work and my Pilot yoke only works sporadically. The landing gear will not raise either. On the warning panel, the Flt Cont light is lit. Can anyone help please. Thank you
