Map update failing after many months & updates, including today's update to 5.6

As per attached screen shot I've been getting this error through the last few versions of Garmin Express and the 5x softwar updates. In another forum someone said this was resolved and hasn't gone into detail about how or what to do. I recently called garmin support in Australia and they said it wasn't resolved and was a know issue. If any of you have managed to get it fixed, or know it to be still an issue please let me know. ciq.forums.garmin.com/.../1297677.png
