keep loosing my POI and home location?

finally got tt5 navigator running on my mda vario after updating TT to v5.21.
it works fine apart from when i exit the application then go back to it most of the POI have been unchecked and my home location isn't saving. so every time i turn it on i have to re do everything?
do i need to move some files about? if so which ones??????

just delete the config.cfg file from the great britain folder
