I feel your pain.Your MSXML is probably a corrupted installation. It is very common for this to happen, and no fault of yours. I also understand your rightful frustration with today's jumble-pile of installed software that we all need to run FS these days: XP, a myriad of Service Packs and Updates, API's, and front-ends, etc.Myself, I am frustrated with the FSX Activation scheme, which, while I support the concept, I don't think the implementation is very watertight. I have been bitten by the FSX crash-followed-by-1722-error now. And I now have zero activations remaining, unless I wish to call Microsoft's activation center (which I should not have to do in the first place).Sometimes I take a step back and wonder just what has happened to our computing world in the last 15 years.RhettAMD 3700+ (@2530 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

>yet there is enough difference in FSX, mostly due to it's airmass flight dynamics>L.AdamsonSorry, "airmass flight dynamics" is a meaningless term.

um that depends how you interpret it, it does mean something if its true the way i interpret it.
