Hello!
I've read in the manual (http://planetside.co.uk/wiki/index.php?title=The_Library#Removing_Items_from_the_Library) that the entire Library can be deleted by using the "Delete Library Database" button in the Library preferences panel. But I cannot find this button. Please, help :)

It's in the program preferences.

I've found you MAY need to click it several times and restart Terragen for it to work...
A-ha, now I see. Thank you!
