jammed

I tried to lower my jib and found that the jib halyard is jammed. It is a roller furling arrangement and this is the first time that I have attempted to lower the jib in the year that I have owned the boat. The sheave at the masthead turns freely and there is a bit of slack in the wire portion...

I am unable to free my rudder after a sand bar collision that pushed the rudder up to starboard...it slid down about two inches when the tiller was removed but will not drop free. I have exhausted many efforts at wedging but still no luck. Anyone?
