So a friend let me use his Toontrack account to see if EZDrummer 2 was something I wanted to invest in. I then bought it 2 days ago and registered it on my friends account. I have proof of purchase from Sweetwater and would like to know if it is possible to receive another serial number. I had no idea what I was doing until it was too late and realized I was still logged in to his account. I really need a new serial number.
