Created Unassigned: SNK issue when trying to build [2455]

I just downloaded this SSH.NET Library. I added it to a new visual studio project and tried to build. There's no code in my "main" project, this is just trying to build the solution and I keep getting an issue:

Error 13 Cryptographic failure while signing assembly 'blahblah\Renci.SshNet.dll' -- 'Error reading key file 'blahblah\Renci.SshNet.snk' -- The system cannot find the file specified. ' blahblah\Renci.SshNet\CSC Renci.SshNet

There's no .snk file in the zip or in the directory in windows explorer. I see it in the visual studio explorer with a question mark around it.

How am I supposed to get past this issue to use this library?
