Hi,Since a few days I have the following problems:On the pos init page I have one line 1 the coordinate N37 55,4 E023 56,6 and on line 2 N51 0,0 W 000 0,0 (standing on EGLL). So my flt planner is lost.On take off I get the next error message:PMDG notification CG not within tolerance aircraft unflyable. I have the trim set at about 5 like normal. You can manually fly the aircraft without problems, but the AP won't engage anymore.I have had in all those years never these problems. I re-installed it again but still the same. Anyone how to solve this?Edit: I don't have the 744, but on other models no problems.Thx,John

John,Check your regional settings in Windows Control Panel. Make sure the decimal separator is a full stop (.) and not a comma (,).Hope it helps,

Thx Mats,That did the trick!!!
