Error running tidal cycles in Atom

Hi! I’ve installed tidal cycles following the instructions on a windows machine. After trying to run a test in the Atom editor I got the following error message:

C:\Users\josch\.atom\packages\tidalcycles\lib\BootTidal.hs:42:41: error:
    Not in scope: `Sound.Tidal.Transition.mortalOverlay'
    NB: no module named `Sound.Tidal.Transition' is imported.

42 |     forId i t = transition tidal False (Sound.Tidal.Transition.mortalOverlay t) i
   |                                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


    Variable not in scope: d1 :: ControlPattern -> b

I already have upgraded everything without any error notification. Any ideas?
