Despite checking the Internet Options and ensuring that my browser is pointed to my preferred domain it always sends me back to i-choice.com. Plus I can NOT send or receive emails. Obviously I can not log onto the web to rectify this, so in laymens terms (aka step-by-step) what do I have to do to delete the corupt file/html extension.
