LE 4 with R16

Hello guys, first time poster. I have a R16 that I finally got my computer to reconize, at first it would tel me my sound card wasnt right for recording, i got the R16 driver for it and enabled it and have been able to open it, but now my problem is I cant get any signal on my computer. I know its going through the R16, im not sure if i have the wrong channels open or set up. Can anyone help? im running a Acer PC with Windows 7 and a 64 bit system i believe.
