I recently purchased a pmdg 737ngx for fsx. When I click on the add ons, then the pmdg option the normal options (eg panel state, options & fuel etc etc) are all missing the only option present is the the "about pmdg option". When use my other pmdg aircraft (the 747 & md11) all the normal options are present.I have a windows 7 64 bit system, and am using fsxTom Gaileytom.gailey@yahoo.com
