Clutch Sticking

I have a '93 Geo Prizm milage: 125K I change the clutch 4 months ago when it went out, now when I push the clutch in and put it in gear after several attempts it sticks, While still having the clutch pushed in and you release the gas pedal it goes. We tried to bleed it but didn't help. I orginally thought that the machnic we just had replacing spark plugs, wires, distributer cap and rooter messed something up. What could the problem be? Like I said it has a brand new clutch only 4 months old. Thanks
