First step would be to check your clutch fluid level. Low? Dirty? Go ahead and do a flush and see if your clutch comes back, though unlikely.

Best bet would be to hit up ZSpeed for a clutch and CMAK kit to replace the CSC and possibly ruined clutch (if the clutch fluid leaked internally from the CSC).

I would start with the fluid, but be prepared to replace everything for full and complete piece of mind that the problem has been resolved.
