Every ten minutes I get a message with alert and icon in notification bar saying google talk authentication failed, then I select it and I get "google talk failed to login. If this is a google apps account, confirm that chat service is enabled for this account." I have tried everything. I have removed google talk and that did not work. when I try opening google talk it immediately goes and tries to sign in and wont let me do anything else. How do I fix this??? As it turns out whatever is causing this is also preventing me from downloading from the market.
