2001 Honda Civic New Clutch Problem

I had a new clutch put in last week. It was fine until a day ago.
From a stop, I put it in first, and the car rattles very hard when I take off. It's more of an aggressive rattle than when a car stalls. I have to put the clutch back in and ease it into moving.
It's fine for the first 10 min of driving. It almost feels like something isn't catching.
Is this a problem with the new clutch or a brand new problem?
