I have a minor problem regarding FSX's default ATC. I mainly fly the PMDG 737NGX, create my flightplan through PFPX and load it into the Sim and the FMC. The default ATC overlay menu thus always provided me with the option to request IFR clearance for my route prior to getting Taxi clearance.
Now, that option is gone and I can only request VFR clearance until I let FSX create its own IFR flight plan through the flightplanning menu, which of course doesn't match the more sophisticated flightplan created by PFPX (which remains in my FMC). The only thing I changed in the meantime was switching from Rex Weather Engine to ASN (wow!), but as far as I know, ASN can only load flight plans to predict weather and does not submit them to FSX, right?
I've tested various routes and procedures (loading/not loading routes from PFPX into ASN) and so far wasn't able to get any of them to be accepted by FSX (although they are identical to those being accepted by FSX prior to installing ASN).
I suspect ASN to be the cause, but I'm at a loss as to why that might be the case and how to fix it. Since FSX ATC doesn't understand my SIDs and STARs anyway and I largely ignore it, it's not a big deal, but somehow I find this strange. Your suggestions would be very appreciated!
