Hey all, I updated my Zenithink ZT 180 tablet to android 2.2. I am trying to access the Marketplace, or even just to register a google account, but every time I enter my existing google account or try to sign up for a new one using the tablet, I get the same message: "Can't establish a reliable connection to the server" I've tried restoring my tablet to 'factory settings' but that doesn't help. I got the same problem with trying to register my Google account before I updated to 2.2 as well. Is there something I'm missing? Is there a way to access Marketplace and register my Google account? Any help would be really appreciated... thanks!!
