MEd suddenly stops working..

[NikkoNinetyFive]

About a week ago I was able to use MEd absolutely fine, but I when I try to load a map, all I get is a black screen.

I read the readme file, and saw the "About my System" in the menu. I see Unsupported Extension: GL_EXT_PALETTED_TEXTURE.

 

So I rolled back the driver's for the graphics to the last version I had, and that was solved but then I saw Unsupported Extension: GL_EXT_TEXTURE_COMPRESSION_S3TC.

 

Then, I just updated again and back with the first error.

 

My question is, why? Why did it all of the sudden stop working?

 

Thanks for the all the help.

It crash sometimes on mine too and I personally do not use it anymore, what you can do is try again on a fresh install or do the changes manually by hand with the notepad.
