when i delete line concerned to bglmanx after i launch FSX it appears again in fsx.cfg why?
The delete line solution, it's not the magical solution to have the problem fixed, and the presence of the line in the FSX.CFG it's just what it's supposed to happen. The module there it's just a way to record that you have (or haven't) trusted the module, so it will not repeat the question each time you start FSX.
We ask to remove the line, only to make FSX forget what you have told it about trusting or not a specific module, and making the question again because, many users gets scared about the message that reccomends not to run the module, so the just reply "no", and of course the program would never run again.
If you don't see the scenery, please read my previous reply, and report back.
