Hi, I'm getting this error when I attempt to load `Assets/AFrameExporter/AFrameExporter`: ``` Assets/AFrameExporter/AFrameExporter.cs(76,14): error CS0117: `System.IO.File' does not contain a definition for `WriteAllText' ``` I attempted to fix it with this and it didn't work: http://forum.unity3d.com/threads/system-io-file-does-not-contain-a-definition-for-writealltext.102090/
