The "Import" feature in the ActiveWords Icon right click menu is used to import data from (1) an ActiveWords 4 database or backup file (*.awdb or *.awbk), (2) an ActiveWords 3 database (*.awb), or (3) a properly configured Comma Separated Value file (*.csv).
The "Restore" feature in the "Advanced" tab of the Options dialog is intended only for restoring a corrupt database for the same user and PC where it was created. Never use "Restore" with an ActiveWords backup file (*.awbk) from a different user and/or PC as doing so will over write license information and create an invalid license.
