Hey,
It all depends on the device you're playing on. If it's on a PC, I can just send you a replacement file. If it's on a smartphone, I'm afraid you'll need to reinstall the game. I've heard there's a way to save your progress, but I won't be able to help with that. In my humble opinion, it might be faster to just skip through to the point you need.
Glad to hear you're enjoying it, and sorry for the inconvenience!
