Hey dude, sorry that's a bug with the Windows Store... I've been trying to figure out a way to solve it for a while but haven't figured out a work around yet. All yougotta do is restart your computer, make sure you have a good internet connection, then open the TouchMe Gesture Studio App again and that should do the trick. Let me know if it works out!I got my SP3 today and installed this app on it - but it's asking me to re-buy the engine! Anyone help?
