Translation:
1 - try a re-boot with the power button - the 'bridge code' should re-install MKK
if that fails:
2 - try installing the 'hotfix' package.
Random question -
Did you just recently update from 5.6.5?
Did you do
BOTH steps when you jailbroke it?

If you did not do that second step ('hotfix' ing the new jb) -
Then you are now screwed (unless you have rp installed).
