"Failed to get archive directory listing" and "Failed to load update data file" error messages

Hi,

This issue was discussed a while ago for the Trados 2015 and seemed to have been resolved by repairing the installation. 

I started getting these error messages recently, possibly after installing the Analyse add-on, which was messy, and its subsequent uninstall.  I can't think of anything else.

Repairing the Studio 2017 installation and rebooting the computer did not help. 

Thank you for advice,

Sandra
