# Why isn't my License Code being accepted?

Check three things. First, the email must be the one you used at checkout. Second, the code must be copied in full from your activation email — triple-click it to select the whole thing. Third, if the code was already activated on another Mac, you'll see that message and need support to release the lock.

If it still won't take, email support@storagestudio.us with the exact message you see.
