I was writing the reply below the =========== line, when I noticed the 2.6d...which is the Macintosh version!
SunLight noticed your version "ET 2.60d win-x86 Nov 3 2012", and Angel asked your version and you replied B.

Are you using a Macintosh?
My startup display shows:
Initializing OpenGL driver
...getting DC: succeeded
...GLW_ChoosePFD( 32, 24, 0 )
...125 PFDs found
...hardware acceleration found
...PIXELFORMAT 7 selected
...creating GL context: succeeded
...making context current: succeeded
Your startup list does not show hardware accel found. Can you run ET ok without DEMOviewer?
Your list also shows only 35 PFDs found, as opposed to my 125. PFDs are PixelFormatDataDescriptors. I wonder if this means you have an old version of openGL or if your graphics driver(s) is/are old.
Some people have reported fixing this problem by restoring an earlier graphics driver or by updating the driver.. I do know that Windows UPdate has offered me innapropriate graphics drivers in the past.
My version of OpenGL is dated 2008.
