Hello, I have just purchase this model (Version 1.4.5) a day ago and I'm having an interesting problem with the PFD's. For some reason the PFD do not work except for the center screens. I followed all the startup sequences (even looking at the jrollon videos) and copied the steps verbatim. The 4 PFD's will not come on no matter what I do. I reset the sim to have the engines already engaged once loaded, still the PFD's are off. What can be the problem? Thanks. Maurice
