2 errors with VS 2013

I just installed the Xamarin.iOS 1.8 plugin for VS and loaded up an existing project. I am getting two errors that I am not quite sure how to resolve:

1. Failed to clean build cache on the server.

2. Identifier is not set in ios application property page (easily fixable).

3. Application name is not set (easily fixable).

Is there any way to force a clean up of the cache on the build server? Is there something on my build server that is causing this issue?
