I have H9Max and H9Core but I can´t transfer presets from max to core. It shows me "The list contained some algorithms which have not been purchased" So please! How can I do that?

Well, both devices need to be registered to the same Eventide account.  With your H9 Core connected to H9 Control, you'll want to click on the Settings button in the bottom right hand corner of H9 Control, go to Restore Purchases, and use the Restore Purchases function to sync your Core with Eventide's server.
