Hello and sorry about the crash!
Please try resetting your data by holding "S" during Clone Drone's startup. If you have current levels you can make a backup of the filepath Clone Drone displays. Be sure to select both reset options just to be sure you get a completely clean save state.
Let me know how that goes. It should do the trick, but if it doesn't I can come up with some additional troubleshooting steps for you. :-)
-Cheers
