Hi Brian, you can jump to the next level like this:
1 Go to C:\Users\YourUserName\AppData\Local\Rewind
2 In that folder you'll find the file "room_Latest".
3 Simply edit that file and change room_n to room_n + 1 (example, changing from room_13 to room_14 will allow you to jump there).
Also, can you please let me know the room in which you were after you change it?
