I installed a fresh copy of serum 2 in a new machine, and Serum 2 was making noise every often. Never had that issue before. Then I uninstalled and installed Serum 2 but kept having the same issue. I went to my account and delete my two machines hoping that Serum would require a re-authorization, but it is not prompting. I cannot find the way to go to the activation screen again. Any ideas?
