PMDG, I am unable to load fuel via the load mgr. as well. I see that you have gotten info you requested for XP and Vista. So far I have uninstalled the product, cleaned the registry and reinstalled the product. I also deleted the fsx config and rebuilt all to no avail.I am running NO addons with the exception of FSGenesis and GEX whileusing the MD-11. I have attached copies of my Config and dll.xmlfiles. Not sure if that will help you in any way.Hope you find a solution soon.Thanks, CraigLian Li PC 65B CaseCorsair HX Series CMPSU-620HX 620W Power SupplyPlextor PX-810SA/SW-BL DVD/CDGiagabyte GA-P35-DS3RCrucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)Arctic Freezer 7 ProIntel E6850 Core 2 Duo 3.0GHz 4M shared L2 Cache @ 3.6 GHzEVGA 7950GT KO 512mb 169.21_forceware whqlSeagate Barracuda 7200.10 500GB 7200 RPM 16MB Cache SATASeagate Barracuda 7200.10 250GB 7200 RPM 16MB Cache SATAVista Ultimate SP1FS Genesis US,Canada,MexicoGEX Active SkyFlightSim Commander VOX ATCTrack IR Vector
