If you are looking for direct assistance, you'll need to engage the Tableau Technical Support team, who will be able to call and work through the issue with you.
If you open the link provided above, there are detailed instructions for downgrading a workbook from Tableau Server to be opened in an earlier version of Tableau Desktop:
Downgrade your workbook
If you need to publish your workbook to an earlier version of Tableau Server or share your workbook with someone using an earlier version of Tableau Desktop, you can downgrade your workbook to a previous version. The downgraded workbook can be opened in the selected version and later.
Any features not available in that previous version will be removed when the workbook is downgraded. The earliest version that you can downgrade to is Tableau Desktop 10.2.
Note: These features are not available for workbooks that include a Tableau Data Extract that has been refreshed in version 10.5. The extract will have been converted to use the new .hyper format and this format can't be downgraded back to a .tde format. For more information about the .hyper extract format, see Extract Upgrade to .hyper Format.
Tableau Online or Tableau Server to Tableau Desktop
If you are using Tableau Server or Tableau Online, you can downgrade a workbook to be opened in an older version of Tableau Desktop.
In Tableau Server or Online, open the view you'd like to downgrade. Select Download > Tableau Workbook and select the version that you want to downgrade to. The workbook will download to your computer.
Any features or functionality that aren't available in the older version are removed for compatibility.
