Can't start a new game

[Penta klavier]

Whenever I try to start a new game, I'm invisible. When I tried to open my menu, this appeared.

Exception: NoMethodError
Message: undefined method `pokedexSeen' for nil:NilClass
PSystem_Utilities:2302:in `pbSetViableDexes'
PSystem_Utilities:2299:in `each'
PSystem_Utilities:2299:in `pbSetViableDexes'

Scene_Map:68:in `main'
Scene_Map:65:in `loop'
Scene_Map:72:in `main'
Main:49:in `mainFunctionDebug'

Does anyone have a clue to solve this?

From your description and the error, it sounds like $Trainer is undefined. This tends to happen when you autorun event doest set up the player or is not set to autorun.
Double check with the example maps.
