"F7" is not working (IT DOES) --> Explaination. That's what I thought at first, but if you are on your boat and have enough resources to make a few upgrades...upgrade your ship. When I pressed F7, no sound and no highlights on the trainer indicator (by Alt+Tab). Only had 4,978 pounds and resources were still not maxed. Important thing is, just remember to hit F7 once only. Doing so, this is what I did. Go and raid and board a random war ship. Any of them will do. Take over the ship when they surrender and just select any ie) repair ship, send captain fleet, yadayada, and low and behold, your $$$ and Resources will MAX out automatically. I went from 4,977 pounds to 43,854,233. And most resources all close to 3000 in red (unlimited).
So to clear things up. F7 works. It does not show umtil you raid and takeover a boat.
You are welcome
