Hi all! We just released another SU09 update today that has a fix for this issue. If you redownload and update Desktop, you shouldn't see this issue anymore.
Edit: If anyone is still having issues, do reply to me and let me know.
I have issues all the time. Unable to open reports or save reports. Sometimes it will recognize my folders on compan server, sometimes it won't. "Drive is not accessible" - "An unexpected network error occurred."
