I've been having problem installing NuGet packages that require Newtonsoft.Json.10.0.1
I just recently installed it and when ever I try installing packages that need it, I get this error:

```
Severity    Code    Description Project File    Line
Error       An error occurred while retrieving package metadata for 'Newtonsoft.Json.10.0.1' from source 'C:\Users\Sharon Umute\documents\visual studio 2015\Projects\sermon\packages'.         0

```

I tried upgrading to Newtonsoft.Json.10.0.2 and adding the path to Environment Variables but I keep getting the same error.
I've checked the path, the Newtonsoft.Json.10.0.2 folder contains lib, tools, and Newtonsoft.Json.10.0.1.nupkg.
I'd really appreciate some help with this.
