I was reading in another section that my settings and song files should be located in:  C:\Users\<your username>\AppData\Local\Packages\Zubersoft.MobileSheets_9fx6hze9e3cne\LocalState. Mine are located in: C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState. Would this matter?

Also, could backing up the contents of this folder and restoring it when the info has been deleted temporarily correct the problem?
