If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
But only for SP2. If you're not sure: just don't.
I don't want to be held responsible but I've done this to about 60 machines for friends so I'm pretty confident of it.
