Well it seem that I am having some problems as of the new patch with the MD-11. I cant get any of my settings to stick when I change them. I have tried a reinstall to no avail. The settings that I am talking about are "Done automatically close windows" "IRS calibration time". Also seems that I can not get the 3 IRS to align any more. Not even if I follow the tut. Please a little help here.FSX with SP1 and AccelWindows 7 (Vista)

The usual culprit under Vista are the security roadblocks. I have UAC turned off; at least make sure you run the installer with admin rights and assign admin rights to the pmdg folder and subfolders. This usually does the trick.
