Unable to put in gear

The car is able to be put into gear when the engine is turned off, but not when the engine is running. This happens when the clutch pressure plate is un able to release pressure on the clutch. When this occurs in can be caused from warn clutch assembly parts and or the clutch slave/master cylinder.
