cant open the level editor for custom Stories

oh dear!
Sorry, but now it´s the same problem
i founded on my computer this:
ATTENTION: System does not support const arrays in glsl!
ERROR: Frame buffer 'Deferred_GBuffer_Main' is not complete! Format is unsupported!
ERROR: Could not create frame buffer for Deferred renderer type: 0!
FATAL ERROR: Renderer #0 could not be initialized! Make sure your graphic card drivers are up to date. Check log file for more information.

a idea is: i have two different graphic cards, Intel and NVIDIA, i re-installed NVIDIA. Should i do this with Intel, too?

im very sorry for this stupid question/problem!
