Not able to contact

Have signed up with Limewire PRO & paid the fee. Unable to get any support as the interface doesn't recognise any of my email addresses as a valid user and guess what, you guys haven't made any provision for someone to email support without entering a valid email address on your database!!!
Could you please provide an email address where you can be contacted in regards to the fact it would appear I don't exist as a registered user. Thanks.
