i am enjoying the mod and already on the 3rd level, i played and saved the game yesterday at night to go to sleep, just now i want to continue where i started off. i started the game with no issues, got to the main menu with the mods background image and crashes just in seconds. do i disable the mod and start again or is it completely screwed?

edit: no i don't have outside mods like the nexus or other mods from the workshop, just this one.
