Problem saving/opening files on Win 10

I’m using Windows 10 and am currently unable to save/open documents to/from any location other than the root of my windows user directory. The error messages I’m getting are:

You don’t have permission to save in this location.
Contact the administrator to obtain permission[/i]

Scapple cannot write to document ‘xxxxx’ and will not be able to save changes.
Error: Access is denied
Choose “Open as Read-Only” to open ‘Design’ with Prevent Editing Mode enabled…[/i]

I’ve tried opening Scapple as administrator but I get the same problem.

Can anyone help with this? (Thanks)

I am having the same issue today. Please help.
