# Why won't Storage Studio accept my payment transaction ID to activate?

Activation no longer uses the transaction ID from a payment receipt. Use the **16-character License Code** from your activation email instead (or the activation button in that email).

Can't find the email? Search your inbox and junk folder for Storage Studio, use the "email me my licence again" option, or contact support@storagestudio.us.
