BLACK (or white) SCREEN PROBLEM: Those of you getting a blank screen right at startup or when inserting a boat, may be running with an AMD Radeon(TM) GPU. This GPU is quite limited but I will soon publish an update (Version 2.8#) to address that particular problem. Thanks to those that have reported this.
You will be able to run the program but with limited options turned on. (i.e: shadows won't show up at full screen)
