Not recording

I have just bought a Lexicon alpha interface which came with Cubase LE 5
it loaded ok and I have trawled through the text to see that i have everything set up correctly.
I can hear my bass in the monitor and can see it in the audio panels of Cubase but when I press record nothing registers despite the record track moving and the seconds ticking away and when I press stop that disappears anyway

Any help please?

Hi and welcome,

Could you provide some screenshots (while Monitoring, while recording, after the stop), please?
