First of all, where did you created your project?
managed to buy the pro :) version created it in the itchu app folder
C:\Users\bumba Studio\AppData\Roaming\itch\apps\easy-fps-editor-pro\Projects\fpstest
Could the space in between the username be a contributing factor?
updated Managed to get the editor working reset my pc should have been inconflict with some software had installed mainly to do with dot net .
Hey, I don't know if I'll have the same problem but when I try to load my already saved game it tells me a fatal error and I don't know why, I don't have dot net installed and I don't know where to download it.
