Value cannot be null. Parameter name: source

I'm having some issues setting up Opserver to talk to Bosun and its scollector agents. I'm not a .NET guy so I don't know much about the code aspect of the project, but I was able to get Opserver deployed to our IIS server successfully, and got Bosun/HBase/OpenTSDB set up and talking.

The issue I'm having is when I click on a server that shows up in the Dashboard for more details, I get the error "Value cannot be null. Parameter name: source". When I remove lines 33 through 36 in Node.Stats.cshtml, it seems to work around the issue, but then of course I can't see the "Services" model.

Source Error:

Line 31: }
Line 32: 
Line 33: @if (Model.Services.Any())
Line 34: {
Line 35:     @Html.Partial("Node.Services", Model)

Source File: C:\inetpub\wwwroot\opserver\Views\Dashboard\Node.Stats.cshtml Line: 33

Any help would be appreciated, and I apologize if this is actually a configuration issue that I missed!
