Hi Daniel.Have you done a 'search' on this forum for an answer ? Many others have had that problem also.I just tried "ctd j41 fix" in the search box at the top and had 9 returned. One of them may have the answer you are looking for.Where you said: "as I go to the folder User / document / xfiles fligtsimulator. I click on PMDG tutorial js4100, the aircraft works well. and as I run the normal way, I not good." -- This has happened to me. I just choose to load the J41 from the "User / Documents" folder, as that way gives the least trouble.I hope you find your 'fix' mon ami.

HelloI made several handling and nothing to do. I uninstalled and deleted, I bought the ERJ 145, which he at least good function and no problem.Tank
