Ah, well i cant help you with that, as i removed the trail before downloading the paid version.
What i can tell you is that even after uninstalling the trail, all my usermade waypoints, my account settings and overall settings still remained in the full version, so thats always good.

Can i be so bold to ask for a feature? A roman number translator would be handy, as ii've come across a number of caches which required roman numbers...
