I have had the trial version of serum for over a year now, it was very annoying to constantly delete serum and reinsert it into FL Studio so I bought the full version. I wasInstalling it and when it finished, a pop up message said that I still had the trail version. I tried reinstalling it but it still said that i had the trial version. so I tried going into the folder where i installed it and tried to move every thing. it still didn't work. how do i fix this?
