Clutch won't engage

Hi, I have a 95 Honda civic with the 1.5L non-v-tec motor... At first the car wouldn't go into gear, so i got a clutch kit from autozone and replaced the clutch disc, pressure plate, throwout bearing, and pilot bearing...then after i put it all together i started it up and it goes into gear fine now, and i backed the car up and started going forward and i heard a little clunk, and now the clutch doesn't engage, i can hear it spinning, but the car won't move. Could this be the slave cylinder or master cylinder problem, or is the pressure plate screwed up?? The slave cylinder looks a little wet under the boot and the pedal does feel a little loose, but i bled it and nothing changed..Can you help me please.. Thank you

Oh I also had the flywheel cut at a machine shop, and you can hear the clutch grinding when you let off the pedal in gear, but it won't grab.. Thanks
