Hi, I have a big problems with WSA Essentials Backup & Sync feature. When I try to use either Magic Briefcase or File Manager, I get an error message that can be found attached. After the error message is displayed, I get different kind of behavior. E.g., File manager does not open up at all, File manager opens up but closes shortly afterwards etc. (file uploads are happening by the way, in that short period of time when File manager is opened). Nothing helps - I've shut down and restarted WSA, computer, reinstalled WSA, but the problems still remains! I've had it since I moved to Essentials from Beta version at the beginning of April (this feature was not available for Betas). I was hoping that it would change with a new versions of WSA, but, unfortunately, new versions haven't helped me. I'm using the latest Essentials version 188.8.131.52 with windows 7 home premium (64 bits).
