For some reason my Minecraft stopped working and the 'Bad Video Card Drivers' error message came up. After playing with my graphic settings for about an hour I fixed it. However, now when I log into Minetown (mc.minetown.net) I get black screen and then it dies. Single player works fine but multiplayer seems corrupt.

Things I have tried:

Deleting all the .minecraft folder and the game.

Restarting my computer.

If anyone can help please do so, Thanks! <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
