i have a brand new android tablet 7" and my market will not download a thing. i have a google account set up and synced to the device and background data is on. i have reset the tablet and created a new google account. it let me download one thing one time only. so i went back and have manually been clearing cache and data from the tablet and the market still does not work. i got on my at home computer to see if i could download games from the market there and it says that i do not have a phone or device associated with my account. what is the problem?? someone please help!!!
