Problem -- Invalid Registration Key Detected Error Message

If you are getting the 'Invalid Registration Key Detected' error upon opening TimeFlow, you probably have custom settings in your Regional and Language settings of the computer that is having this error.  For example, you may have the Format set as 'English (United States), but your Short Date format is 'dd/mm/yyyy' (day/month/year), which is NOT a US date format.
If you don't want to use your country's Format (in order to keep the English language on that computer), but you wish to keep the date format as day/month/year, we suggest that you change your Format to 'English (Canada)'.
