How can I find the solutions to the Lost Hotmail Contacts isssue?

A couple of weeks ago I started getting l"ow memory warnings" but my Hotmail worked normally.  This morning I went to send an email and my entire Contacts List had disappeared.  I got the memory problem solved but cannot find a way to get my list of contacts back.  When I go to Contacts (People) I don't have any options, like manage, etc.

Is there anything I can do to recover my email contacts?

Thanks
