I wanted to test this wonderful addon on the other hand fell to a real disaster. when i launched the fsx addon does not respond and the game closes all by itself. i then try to reinstall fsx and the addon but still the same problem. so i decide to restoring my computer still has the same problem.

When you say "launched the fsx addon", do you mean when you started FSX?

No need to reinstall FSX neither restore your computer. Don't worry, it's just something that caused it to crash. We can see it in UGCX.LOG file. This LOG file is created every time you launch FSX. This UGCX.LOG  file works something like an aircraft's blackbox, if FSX crashes....we can still go back to that LOG file and check what it was doing before FSX crashed. Analyze it, and then provide a workaround or fix to it. Remember that all users machines aren't the same, there could be few that it could fail, and that's why the LOG is there, so we can analyze it and provide a solution to any error/crash.

The log is located here:

C:\Users\<username>\AppData\Roaming\Ultimate Ground Crew X\

The log file is: "Ultimate Ground Crew X.LOG"

Paste it's content here.
