Unity error preventing me from test playing my game after installing 2D Gamekit

Assets\2DGamekit\Scripts\SceneManagement\CharacterStateSetter.cs(107,82): error CS1503: Argument 2: cannot convert from 'method group' to 'Action'

This is what pops up in the log when I try and tedt run my game. Then I tried to delete the 2D Gamekit from my files, It did let me test my game but it was broken. (Colliders didnt work, and alot of things that where supposed to happen wouldnt, I think my characters somehow became dependant on the scrips, I dont knoe though just a speculation). I reinstalled it now. I have no understanding of C# or any other language. If you could provide a sollition it would be amazing. This is for school. I can provide the code of the problematic scrips if needed, but I cant right now. Thanks and good night.
