Sometimes you have just added information to your Legacy file, but you don't see the new information in Charting Companion.
This is usually caused by opening an older version of the file in Charting Companion.
To make sure that you are looking at the most recent version of your file, make a note of where the file is located in Legacy.
In Legacy, click on "File, File Properties":
Legacy will tell you in which directory (folder) the file is stored:
In Charting Companion, click on "Help, About" to display the folder where the files is located:
CC will tell you in which directory (folder) its file is stored
Note the file name in the Title Bar:
If the file name & folder are not the same as Legacy above, click on "File, Open" in Charting Companion, and browse to your most recent Legacy file. Make sure the file is not open in Legacy at the same time.
