The engines in LuxCore were renamed a while ago, and LuxBlend didn't include the necessary changes until yesterday.
So you need to update LuxBlend, e.g. by opening User Preferences and using the update button in the LuxRender addon settings: http://www.luxrender.net/wiki/LuxBlend25_LuxCore#Updating_LuxBlend [^]
