Hi
I wanted to keep this separate from my other thread. 
Reinstall MobileSheets
Go to reinstall settings from a custom directory 
Pick a file - in my case the most recent
       Storage location error which says to click ok to grant access. 
       Click OK to grant
You get taken back to the directory, but with no files showing - though they are still there on disk. 

Set the storage under the settings 
Try to reinstall the settings from that location
     Storage location error message and disappearing file problem again. 
Restart MobileSheets and same error

However - it will allow you to reinstall the whole library, so it is just a problem with the settings. 
* After importing the library I still cannot import the settings. 

So can I save settings there - yes
Folder security on J:\MobileSheets Storage  is set to Everyone having all permissions
I copied the mcf file into
 C:\Users\AndyT\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\TempState
I get the same error
Deleted  J:\MobileSheets Storage
Recreated  J:\MobileSheets Storage
Same error
