Microsoft Expression Web and TLS security mechanisms

Good Evening All, A lot of Microsoft Expression Web 4 users, myself included, have recently experienced problems uploading files to servers as the software doesn't seem to be able to be able to communicate and comes back with an error code of - Please reconnect using TLS security mechanisms (421). Filezilla doesn't have this problem, but I am not a keen Filezilla user. Is anyone able to reconfigure the settings in Microsoft Expression Web to get around this problem?
