Minecraft Error

Hi guys I get this error after logging in on AnjoCaido's cracked client.[IMG]http://i1098.photobucke*****m/albums/g380/armandqc/ErrorMc.png[/IMG]
Here is what it fully says

Bad video card drivers!
-----------------------

Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.
