Hi, FolderShare friends,
There's a new version of FolderShare for Windows that's designed to help improve security and reliability. To bring as many people as possible up to date, we'll start prompting users to upgrade this week. When the time comes, you won't be able to sign in until you update. We understand this process may cause some inconvenience, so we strongly encourage you to get a head start and install the new version today.
Thanks for your patience as we get FolderShare into even better shape!
