I completely uninstalled all the QGIS I could find on my computer and then reinstalled the 64bit version of QGIS 2.8.9 stable release. Once I had done that the plugin worked properly.

I got to ca. 30km georeference error, and my tie points are almost on a straight line. Using 7 points more equally distributed I get the error down to approx. 25km (more on the east coast, see image). I used these tie ...

Use BricsCAD, which is in fact an affordable copy of AutoCAD. This software is able to read the geocoded information of a geotiff.
