Exactly. I tried the game without the trainer and it crashed within 5-6 mins every time. When you turn off the V-Sync you still get crash, but every 15-20 mins. So save often. The trainer has NO IMPACT on crashes.
As for Super Pirate and Super Ship, I'm not sure how to make them work properly, but to be honest, infinite Gold/Toolbox/Rum make you already near-immortal ^_^ So I'm not asking for more.
