Before you follow danifunker's market instructions, you should follow jefftheworld's Rooting your Vox guide:

It goes very clearly through the steps you need to take prior to installing market. As I said, once you get to the market part, I will be unable to help since I have not followed the current instructions. I just want to make sure you have accomplished the necessary preparation (and to be clear, you cannot skip steps in any of these instructions...there is no shortcut).
