No My Book Live Found... it use to work

I wish I had never bought Mybooklive - it is the worst! I can not get it to work anymore and yes, I have downloaded the latest software for the computer. It is such a pain. Can anyone help? I am on a mac, running 10.8.2 and it no longer sees MyBookLive - I should have saved myself the stress and purchased from mac… won’t make that mistake again. In the interm -  How do I get this horrible thing to work? Please someone help!

Have you already map the drive?
