Unity client crash while validating integration

I'm on the 3rd step of the Basic Integration, I've just put my Cloud ID into player settings, and when I hit the Play button in the editor, the Unity client crashes to desktop. Anyone have any idea what could be causing this?

I'm running Unity version 5.1.1p3 and have not used any Unity Analytics related packages in the past. There's no Analytics code written yet, the only alteration I've made to my project related to analytics was pasting in the Cloud Project ID. Prior to that change, the project compiled and ran as expected in editor, and was able to make Android/iOS builds, etc.

On the Unity Analytics page I can see 'Basic Integration in Progress...' just under the Basic Integration steps box.
