i updated my graphics card successfully, but it still says cant connect to minecraft.net"
also, idk if this means anything, but when its downloading in browser it says it's a jar file.
btw my bro is playing it next to me, so its just this computer with the problem
I helped you update your graphics driver, which is what you asked for in this thread.
If your having problems connecting to minecraft do you have another thread with this question? If not, make a new thread as this title is misleading and you'll gain a larger audience.
