My AOL email has stopped working. I've tried clearing the cache, clearing out and re-entering my password. I can't delete the account - I've tried repeatedly, but since it is the default account and that can't be changed, deleting it is out of the question, I guess. I haven't gotten any new mail in over a week. Taking the battery out or shutting off the phone and restarting don't work either. I'm out of tricks. Help, please. Thanks.
