EMU 1616m (cardbus) not offerring its input sources...

Hi. I bought the EMU-1616m to use with my laptop. i am using reaper to record a microphone and guitar input through the EMU, but when i try to assign the microphone to one track and the guitar to another it doesn't show any input sources coming from the EMU. it should say something like "A-Hi Z mic input" and B-Hi Z mic input" as options to pull from, but it doesn't. it doesn't seem to understand where the sound is coming from at all. everything comes through as one generic source and if I sing through a mic and my friend plays his guitar through the other input they both record to the same track.

Has anyone else had this issue with the EMU? Can someone give me a suggestion as to how to get the input sources to show up or even what to look for when picking the input sources in case they are not called A-Hi-Z, B-Hi-Z? thanks!
