I have a Mac OS X 10.7.5. trouble playing from USB turntable

Just purchased a USB turn table and want to play and save music on my laptop to share with other devices.
I downloaded the Audacity Version 2.0.3 and the quick help screens were not the same as mine and i think I have set something up wrong.
Any help would be appreciated.

The current version is 2.0.6

There is an article in the manual (included in the recommended download) about recording from USB turntables: http://manual.audacityteam.org/o/man/recording_with_usb_turntables.html
