No Resources.Load() avaliable

I may be missing some big thing here, but I'm trying to load a prefab/texture into a GameObject and Texture 2D, but there's no definition in Resouces for the Load() method. Heres an example. The error I'm getting is: 'Resources' does not contain a definition for 'Load' . It's happening on my other computer as well, and Unity is updated on both of them. I've been struggling with this for some time, and help would be greatly appriciated.

public void NewWaveStart() { GameObject Enemy = (GameObject)Instantiate(Resources.Load("Level1Enemy")); intermissionTime = 20; waveNumber++; }
