You should have a file named yahoo_ab.csv. If you did not see it on a screen during the export procedure, then you need to repeat it. I had to click on Export twice before it responded. Or, perhaps the user just needs to click once and wait until the export screen that shows the file appears. But, if it does not respond after some pause, click again. It will be saved to whatever folder you have set at the normal target (folder) for downloaded files.
