Please Help Me! The game don't run!

When I open the game It appear a message: undefined method screensize for String

I’m on 1.2.2 version Windows

Hi this sounds like save file corruption, such as when the game is exited in the process of saving, for example. If you navigate to your C:\Users(you)\Saved Games\Pokemon Insurgence folder, delete the Game.rxdata, and there is a chance that if you rename one of your Backup files in the same folder can be renamed to Game.rxdata and rescue you

Thank you so so much!!! I’ll try it when I have time!

It Works!!! I’m so happy, thanks so much for the help and sorry for my elementary english.
