ActionScript 3.0 :: Saving Flash Data Into New Row In CSV/ Excel?

Half way through;user saves the answers to a CSV file to a location.then continue the test and save the 2nd part to the same location (different file name). The next person completes the same test, and theoretically saves in the same location OVERWRITING the file. HOW IT SHOULD WORK when they overwrite the file, it SHOULD add it to the next ROW in the excel (csv)document, not overwriting the WHOLE file. In the end, you would (in theory) have a number of rows in one excel document, each row, a different user who completed the test The issue is: on the MAC computer, this works (im not sure if it's because the previous developer developed it on a MAC) however when I play it or move it to windows computer; It overwrites the whole CSV file, and doesn't add it in the rows.Here is the main code (half way through) for the first save:

Code:
stop();
qNum.text="Q 11-13";
