2) What error do you get?
Have you added email for the contact form (Theme Options > Contact Form)?
Make sure that Mail function is enabled on your server. Contact your hosting provider and check mail logs, make sure that mail function works fine from the server side.

The issue with the contact form is that it just does not send, or present the confirmation graphic that it has sent. It used to work. I have tried disabling plugins to narrow the issue, but to no avail.
I have offered you login details etc. privately.
