Accord 4cyl 5speed won't shift. 124,000 miles

The clutch slave cylinder was going out, so I purhcased a new Clutch
Master Cylinder, Slave Cylinder and the line from Honda. I installed
them and the car ran fine for about a week. The cylinders are holding
pressure and fully extending the clutch arm. Now the car doesn't want
to go into any gear. If I turn the car off, I can change gears, when
the car is running and in gear with the clutch pressed to the floor the
car doesn't leach forward or give signs of the cylinders slipping. I
suspect the clutch disc is worn and needs replacing. What is your
opinion.
