I logged into my account yesterday and was told I should update my data as per new calculations and that it should only take a few minutes. Its a day later and whenever I click on 'View Data' (it still says all my contributions are there), the page loads and still says No Data Selected. Should I just keep waiting or do I need to do something to retrieve my data?
everything is fine. Your contributions are all there and have been re-calculated. As it says, no data was selected, so you have to select data to view, by creating a series. Please see the tutorial and the help on series.
