Thank you. That did the trick. But why does this seem to be an issue, especially after updates?

Updated to newest version of RDM a few days ago. After starting up RDM and logging into my Devolutions Online Drive, I can not see the tree of connections in the left hand Navigation window, instead I see a big red X. It looks like the scroll bar is working as if there are listings there, but they are not being shown. I can see recently opened connections, but "view entries from your current data source" has a the big red X. Can someone please assist?
