Following these instructions to the point worked perfectly for me. Thanks Davide for the excellent support and quick reply!
There was some differences in labeling between the instructions and the IDE i installed, so just to clarify the first paragraph of the instructions, this is what i had to do to install arcore:
Go to Files->Preferences in the IDE. In the field labled “Additional Boards Manager URLs:”, type
Go to Tools->Board “<board name>” and select “Boards Manager…”
Now click on “Leonardo & Micro MIDI-USB (arcore)” in the list of additional boards and click the install button that appears.
