1) Go to Administrative Options
2) Go to Import/Export (second line at the end) click
3) Go to Export all Amazing Charts templates to an XML file (1rst column4th down) Click

I don't think it has changed much in many years, this should work.
Then try to import
You can always check it in a browser, but it should not look like a row of tables
