Okay now I am the one who is confused.
I downloaded Dark Basic Enchancement on my other Computer, and there is no warning about a 30 day trial. And I use DLL for some collision. And everytime I do boot up Dark Basic, it still says at the bottom of the screen, Dark Basic Enhanced Version. I didn't pay a cent for the enhanced version. Anyway, I use Dark Edit as my primary editor, but occasionally check up on my Dark Basic Version. So you know, it could be that you are using a trial, but then again I have no idea on earth why that is happening to you. Good luck dude.
Games I am releasing:
Dragon Stone I : Journey to Achilles Dungeon - 2006?
