CS 2009 issue – An item with the same key has already been added.

I ran into this issue while setting up CS 2009 on my local box. Funny thing is, this issue is fixed just by reactivating Commerce Server feature. I think recreate the channel configuration list and refresh the dictionary which add default channel name.
