Hello

Was wondering if someone could help me please.

I have successfully setup my email addres as I am able to receive emails. I
can't however send emails.

My problem is that my contacts have disappeared and when I try and open
addresses in the tool bar I get the message

Unable to open address book. The address book may not be installed properly.

I have recently changed service providers however this problem occured just
before the change over.

I need really simple steps to help me fix this problem I am not very
computer literate UNFORTUNATELY.

THANK YOU
