first off I'm not really computer smart, but i have been playing entrenchment v 1.041 for a while with no problems, I even played yesterday and it was working fine, but today i noticed there was an update available v 1.051 but when i went to update it said my registration was not valid. I don't see how it is the key is exactly right and i only have the one email, I've updated the game before just fine, I don't see how all of a sudden its not valid.
And when i tried to play v 1.041 again it asks me to activate my copy of entrenchment, which i cant do because my email or the serial number doesn't work anymore for some reason. and again i only have the one account with stardock so my email is correct the serial number is exactly the one they gave me when i purchased the game.
