Once you have setup your Mionet account , go to www.mionet.com and click the Sign in link at the upper right corner of the webpage.
Then you enter the mionet user account name and password which you already created and click the Submit button.
From there the interface will open and you can access your folder and other shares.
Note: You cannot access your folders from your local LAN. You need to access and sign in from outside your home network in order to gain access to content in the shared folders.
Additional user guides are available on www.mionet.com or refer to the PDF user manual on the CD that came with your unit or www.wdc.com Support site that has a brief intro to using Mionet Remote Access
