Ok , last time i did mine I bled it like this. Open bleeder, have your helper push the pedal to the floor slowly, until its down , close the bleeder . pedal up. Do this 9 of 10 times.
Of course keep the master full. Then bleed like normal, pump, pump, pump hold ,open bleeder , pedal to the floor , close the bleeder. Then if that dosnt work. I reverse power bled it with a brake bleeder. I emptied the master, hooked up the power bleeder to the slave nipple and bled it backwards. Until the master was at the full line. That seems to be the best way.
Usually if its not bled, you can't get the pressure plate to release to get in gear. But if you can get it in gear and take your foot off the clutch, and its not grabbing. Something is hanging up. Try bleeding again. If that dosnt work , recheck the disc. But if it is facing the wrong way, I don't think you could get it in gear. IIRC.
