When I upgraded from trial to full in Plant Tycoon instead of sending me an activation key for my trial version I had to download a whole new game and was instructed to trash the demo before installing the full version. Does this really mean I have to start all over agan? I've been playing for fifteen hours and just did get enough money to upgrade to the good soil. If this is really how its going to be we need to be warned first. Please advise. I'm on the verge of sliding into a deep and dark depression.
