Audio Interface

Hey There all,

I have huge problem, since 2014 i bought this copy of CUBASE LE 8 and i have a registered License. I have no issue on converting and exporting files. But my biggest issue is i cannot use my external microphone for recording. I have Zoom H4n Handy Recorder which is pretty good for sound, i have ROde NT1 Condenser Microphone which i can easily use using on board +48 V Phantom power. but when i connect audio interface as ZOOM it wont work either for mic or for output.

iam using HP Note book.

Can any one explain me why and teach me step by step if i am missing something. I made system AI also zoom but there also its doesnt work for.
when i use Studio One it work for output but not input.

Plz i need Help.
