Reply to HELP! I cant use my launchpad with traktor pro 2!

Okay, so i bought a novation launchpad off a friend and i cant get it to do absolutely anything >.<
i'll say right away that i am a total noob with controllers and anything midi. ive got traktor pro 2 running on windows 7
i downloaded the usb driver for it, since windows couldnt even find it on its own, as well as a tsi file with the mapping already done, and i load it into traktor and i closed and restarted but the launchpad does absolutely nothing! help? :<
