NifSkope 2.0.0 Pre-Alpha 6 Error

[Dumbbus]

I didn't know where to post this but whenever I run NifSkope on my computer I get this error.

 

fo4_env.frag:

ERROR: 0:2: '' : extension 'GL_ARB_shader_texture_lod' is not supported
ERROR: 0:273: 'textureLod' : no matching overloaded function found (using implicit conversion)
ERROR: 0:273: '=' : cannot convert from 'const float' to '4-component vector of float'

fo4_env.prog:

depends on shader fo4_env.frag which was not compiled successful.

 

And I have to click okay but other wise the program works fine, but I wondered if there is a way to fix the error.

 

I don't have FO4 because I haven't purchased it yet, I just have FO3 and NV, but I check the shader directory of NifSkope and the file fo4_env.frag exist in there, do I need a different compiled version or am I using the wrong version of NifSkope.
