Actually that had no effect as it wasn't in there.....
It turns out that my client.cfg had been wiped clean, losing complete UI setup inc. macros.
As I've never been required to back anything up whilst playing an mmorpg before I wasn't aware that is was advised for this one so I was in effect up a very smelly creek without a paddle.
The only way I had to get around it was to copy what was contained within the client_default.cfg into the client.cfg. As I said, lost anything that I had done to UI and macros so I wasn't a happy chappy, but on the bright side, I can play again
