This is really frustrating!! After resolving another similar error, now all of a sudden, the Market on my 7015a no longer opens, and I will sometimes get this error. Sometimes, the market just will not open when I tap on it, other times, it does not open and I get this error. My tablet was rooted, I installed the graphics fix, then the Market. After I resolved the other error, the tablet was fine. I have not installed anything on it since. Yesterday I turn it on, and "poof", no market and this error. I have done a Google search on the error, and there have been several fixes for other people, but they have not worked for this tablet. One fix was to go to Settings-Applications-Manage applications, then delete the cache for the Market. The market no longer appears under manage applications. I reinstalled it, but still nothing. What could have happened????
