Reply to DJing internet radio HELP!! UGH!!

OK this is extremely confusing and down right nuts in some parts, but bear with me and may the gods of audio see me through this mess.
First of all lets start with gear:
Alienware comp running vista 64b
creative audio crap in the comp (i swear it never worked very well but that is a different story)
hercules dj console remx
vdj (comes with the rmx)
sam4
vdj pro
tons of cables wires headphones and goodies
just got a windows 7 lap top

OK now the problem:
I don't have one friggen clue how to get this set up to work.
I can use vdj, I can use the rmx, I can get it to work in a real world situation... but trying to get this damn thing to run into an internet radio station is kicking my butt.
(shameless plug) If you wanna spin on the internet radio give me a scream.. it is fun.. thats it.. fun no money haha)
The one station tells me that all I need is to send the rmx from output 1-2 to the line in on the comp.. well i have like 4 line ins and I cant get it to work..
Do I need to run the line in to a different computer maybe. Will this not work on the same comp both ways?
ANY SUGGESTIONS will be so greatly appreciated I may do crazy stuff like sing happy birthday Mr President in my boxers while doing the cha cha at the next live show..
