Only the Bossland GmbH front office ([email protected]) can assist with problems like this. The forum Support team has access to neither the tools, nor the user account info, to assist you with the problem.
When mailing the front office, you will need to describe what you want, and prove you are the owner of both accounts. This requires the email address(es) associated with each, and the transaction IDs used to purchase Honorbuddy for each. If you fail to provide this information in the initial contact, the first mail volley will be asking you for this information. So, it will speed things up if you just include it to begin with.
