Do a search on here re. bleeding these things.
I posted something about it not that long ago.
Pour fluid in the top until it runs bubble free from the bleed nipple.
Then get someone to slowly deck the clutch with the nipple open... as they reach the floor tighten the nipple - repeat checking fluid as you go.
At night, jam your clutch pedal down with a stick and leave it overnight this lets the system self bleed.
After a few days it should be fine.
