So I thought things were going along pretty well with getting everything uploaded from Dropbox and putting my files in "collections", then noticed that when I clicked on the import from Dropbox - it displayed only a partial list of what is in Dropbox.   Why is that?  I spent a great deal of time getting my folders in Dropbox all arranged in "collections" so it would be easier when uploading to my collections in MS, but now MS doesn't see what is in those dropbox folders.  In some cases it shows NO files at all!  

So, since it wasn't recognizing my dropbox files, I then tried (from the Companion) to select files from my computer - seemed to work but now when I click to open a file in MS, it is a black screen with very small print that says File/storage/extSdCard/Android/data/com.zubersoft.mobilsheetspro/files/ "name of file"/ does not exist

I cannot get ONE FILE to open!  What have I done?

When I first installed MS, I chose the "manage files myself" option. (probably shouldn't have, because I have no idea what I'm doing) but I proceeded to merrily upload files and view them, thinking this is just great --  until all my files became un-viewable.   I tried switching to the "let MS manage my files" option, no change.

Other things I've tried:
I don't remember specifying to put my uploaded files on the external SD card, and I didn't want them on it, so I deleted them, thinking that was what the problem was, but then wondered if MS put the files on the SD card, without my knowledge.  Either way,   No change, still the same black screen/file does not exist message

Also, I tried "clearing" all files from MS, and it took a very long time for it to delete the files, but then..... the files were all still there!   Weird.    But still  won't open 

I'm afraid I've really messed it up, so now what?

Should I uninstall and reinstall?  Help!
