Hey, you key has been reset. Please check.I'm also having this issue. I switched my license to an older Mac Pro temporarily, and after deactivation on that machine, I can't activate on my main machine. I've since installed a trial key. I've tried trashing the license.xml file, and the accompanying sudo command in terminal. Nothing.
Can I get you to reset my account and key as well.
Much appreciated.
