Hi SRSilv, welcome to our forums!
Actually the tutorial free pack message is one of the newest features in the software. Once you completed the tutorial, a free pack is added to your account, if you are logged into one in the software. If not no worries, just enter the same credentials on the login screen you used when registering to the site. Once logged in, you should be able to claim a pack of your choice on your Profile page. If you are using the Steam or Google Play versions make sure to untick Steam/Google Auth before logging in. Also clicking the “Earn more” button on the free pack counter will perform an automatic account linking if necessary.
I hope this helps, but please let us know if you face any issues.
