I realize it has been some time since the last note on this thread, but I thought I'd give it a try. I played Plant Tycoon fairly regularly some time ago, and was using the Virtual Seed tray - delightful little invention! Haven't played for 2 or 3 years. I came back to it yesterday, and worked on my existing game. It worked yesterday and even some of today, but after playing for a bit today, when I went to open the VST, I got an error message - "You do not have an active PT Games. Start a new Game in Plant Tycoon." So I started a new game, and I still get the error message. Can you give me any tips on how to get things rolling again? Thanks.
