Thanks for suggestions. I've already installed the Turbine plugins. But it still doesn't work. When I use the call as Fortunis suggested, I get the same error but in the main.lua. All other plugins work perfectly. I suppose the file structure or naming is wrong. My directory looks as follow

Plugins
+->Fido
   +-> simple.plugin
   +-> simple (directory)
       +-> __init__.lua (is empty)
       +-> main.lua
       +-> Window.lua
