I un-installed EZDOK then re-installed it. When I started FSX this is the pop up I got; Ezca for FSX has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.It is installed in my J Drive where everything else is but not directly in FSX.

Your security license may have expired. Redownload it from flight1 and reinstall. It's happened to me and several others on avsim. If that doesn't work uninstall and maybe run ccleaner and make sure it's completely gone. So it's not installed on the fsx drive? Maybe that's the problem.
