Cracked Minecraft with Mods and Texture Packs?

Okay, so my Minecraft through Mineshafter (http://mineshafter.info/) isn't working. Whenever I enter my email and/or username (I've tried both), it won't open my account. So I'm trying to find a cracked version of Minecraft that allows me to use texture packs and mods. Please let me know if you find one. Also, if anyone can help me fix my Mineshafter problem, that would be great.
