I can no longer trust this application

After the last upgrade I lost my data for two weeks. The new version restored it, but unfortunately not my confidence in the application. This was compounded by unhelpful instructions on how to recover data that wasted my time and an explanation that it was taking so long to fix because of "a major design flaw." Somehow I didnt find that very reassuring. Had this happened at the end, rather than the beginning, of the semester it would have been disastrous. It may take a little more time to set up, but I think Ill stick to a Numbers spreadsheet from now on
