Clutch or Transmission problems?

I would appreciate any help I can get. My Probe is a 96 GT. I was driving and came to a stop sign, heard a small thud and let out the clutch to go and didn't move. Everyone said it's the clutch. It's a 5 speed manual. So I put a clutch kit in along with a master cylinder and slave cylinder. I still have the same promblem. Put it in gear nice and smooth let out the clutch and I go nowhere. I put it in gear without the clutch in and still the same. Can't hear any metal grinding or anything but I can here what sounds like turning as if I'm supposed to be going somewhere but no movement.? Any suggestions?
