Can’t help with send owl, but with regards to the unactivating, I’m not sure if I do it correctly, however I go into the the order (I use subscriptions so find the parent order) and then find the custom fields and delete the xls_padlock_xxxx field. There is also an option in the help file to add a switch to the executable to remove the activation from a PC, to force entry of a new key here , but I don’t think that would help in this instance
Good luck with the SendOwl question
