Feels like it might be a corrupted download? Or else you're using a non-windows version in JoiPlay.
Try downloading the CK v0.19.9 - for Win/Linux version again and see if the issue is corrected. Failing that, see if attempting to load a different save file works (I recommend the autosaves - tap "A" on the load screen, to the left of the page numbers - as they occur every time you sleep and are always "safe".)
