Click the computer listing itself and a window will appear on the right with it's backup destinations.
Click the arrow to restore from the location you'd like (see screenshot).

Note that the web restore is limited. It is not designed to restore an entire user profile or drive. It is designed to restore a folder of files or a single file. If you get the message that you have selected too much to restore, please contact MacLab to see if we can increase your restore limit.
To restore a large amount of data, use the Crashplan software.
