Recording problem - Lexicon alpha (Help!!)

[chozartmaninoff]

Hi,
Just purchased a lexicon alpha recording unit, it comes with cubase lite. And it all plugs upto my laptop. Ive done some recording on it and it records fine, however it only plays back through one speaker or one side of the headphone.

Its not faulty headphones or speakers. I think im just not doing something correct. Does anyone have and idea of what to do or what im doing wrong....?
Many thanks guys
