Ok, here we go again. Uninstalled it, and reinstalled it. Nothing. Same error. I click on the 'configure' application for the software (it's like a manager for updates and what not) and I get error 429 again, but this time I get: "You do not have an appropriate license to use this functionality" ...which is pretty stupid because I have the keys to validate the software, but I can't do that until I get the application to open! I'm running low on ideas.
