Geez Rob, hope you get it sorted...I can imagine how frustrated you are.
I have decided not to purchase the add-on and wait until another 12months when some more bugs ironed out.
Thanks to everyone who has commented on their personal experience.
As noted above, I have received excellent service from BLA Brisbane re: my Terrova when it had issues - so I am happy to hear they are keeping up their good reputation.
Let us know how you get on.
Cindy
