KB10347 - Registration/World file created with other GIS software product is not visible.
Some (non-TatukGIS) software products assign crazy dates, such as thirty years in the future, to World Files generated during rectification, which the Borland code (for some reason) in the DK does not accept. Check if your TFW (JGW, etc.) file has a logical date. If not, change the date to something reasonable, and try again to open the file in the DK or other TatukGIS product.
