Ahh thank you so much, that worked perfectly!

Hey guys, just as the title says. My Windows 10 O.S. has updated to anniversary edition and now my LFS license needs to be reactivated. When I go to my account info it says I still have 3 keys remaining but I can't for the life of me locate them. I have checked in my email history but could not find an email containing the keys. A little help here would be much appreciated as I am at a loss
