I used Sandboxie 5.19 during the beta phase for a few weeks with Microsoft Office 2016 sandboxed (Word and Outlook) and faced only a few problems, that didn't stop me from working.
With the latest stable release 5.20 and Office 2016 with the latest updates from june, I get following license error:

The error message tells me, that the office license cannot be found and Office is getting closed.
I opened the program again in the sandbox, to view the status of my license:

The license is not shown and the whole submenu seems bugged. Don't know what's wrong here.
When I open the program without sandboxie, the menu looks like following:

The product is activated.
Can you fix this error please?
Thank you.
