When I start Studio One 3, I get a pop up for activiting it, this is an eternal loop, neither click ok or manage activations helps.
Manage activations brings me to the my presonus, where see and can download my license file, but both options just restarts S1 3 and it all begins again. Since I never can start it I can't activate it.
Well, while writing this I got an idea.
C:\ProgramData\PreSonus\Studio One 3\ is the directory where tthe old license is.
I deleted it and now I get the option to activate it ;)
Hope this helps anyone,
