Windows 10 Exception Error

I’m on Windows 8.1.

Just downloaded Version 2.4.1, 64 bit. Typed Tablo in the Select Tablo box. Hit Refresh. Get the same error, “Unexpected Exception/Exception: The underlying connection was closed. An unexpected error occurred on send.”

Do I need to download the latest version of Tablo Ripper? Is there something else I need to do?
