Reply to Need help, I'm lost: traktor pro 2 / s4 / ableton

Ok, just don't throw me stones yet: I'm made my researches first and what I've found are half answers, tutorials for mac, threads were few answers were given, etc... I'm fully aware parts of my question(s) have been answered partly somewhere but I'm just lost. I have seen endo's tutorials, Armyofme's one but that wasn't of any help either. I checked blog entries from djtt but as they're quite a bit old, they didn't help too. I used Google and different searches here and on NI's community , I really tried to do my homework before asking but if one could give a hand, that would be awesome (and you'll get eternal recognition, you'll get cookies and lot of maidens in the after life, I promise - well, kind of).

This what I'd like to do:
I want to route the sound coming from tp2 to ableton so I can use vst effects on that. I don't want to route each deck individually. I do have a pc 'so get a mac' isn't a viable answer. I've used Loopbe1, jack audio, tried and tried and tried but really no luck. I'm lost with jack audio, not sure about the settings. Only managed to get a signal from TP to ableton it seems but then no sound coming out from ableton. In the end I'm not even sure I can do that with only the internal soundcard of the s4 (and eventually the built-in one from the computer).

A clear step by step for dummies like me would be great. And if one exist (for windows), now you can send me stones.
Please? Thanks in advance.
