I tried the same thing with MC Patcher and the only buttons were Open and Cancel I tried using TextureEnder.jar but WinRAR was the default program. I tried to use Java TM SE Binary but that wasnt popping up.[Im using Windows 8]
My Dell computer never gets this error [graphics are rated 4.5] My desktop has the latest Java,and I watched all of the one for Windows XP and put the slider to below half but no OpenGL and I dont know how to unistall video card drivers
I'm getting the same problem. Except I deleted the .minecraft folder saved my texture packs,my worlds,and I clicked force update twice, and I saw "Account migrated, use email as username." and Not downloaded popped up! Force update needs to be updated!
