Issue with Live contact import

[James]

thanks for writing this module, you have made my life easier for importing contacts on a website I am building. however, there is an issue with importing from Live for me. Your code is looking for a field called 'account' but while it exists, all my contacts have something under 'preferred', and 'account' is always blank.
