As I follow this mess unfold, it makes me very thankful that I play John Tiller HPS and JTS games, since they would never ever pull anything like this on there customers and game owners.
Too bad you guys can't get together a boycott their games and/or any new releases. If you don't like the way they do business and the way they treat you, hurt them where it would hurt the most, in their sales!
Since I am not a CMx2 game owner, I had an idea that I wanted to mention to you guys. Is there any way you can uninstall your game and reinstall it up to the last good working update?
I know that this will not help you out in getting what you paid for in that lousy 2.0 add-on update however, at least you guys could play your game and not have to jump through hoops to try and create your own work-around.
