I have a profurl furler which always worked well until one day the genoa unfurled halfway and stuck. Fortunately I had a large crew on the boat that day and we were able to alternately muscle the sail in and out until it was all the way out. When back at the dock I re-greased the bearings and the problem didn''t reoccur for a few months -- until a day I was single-handing. Luckily, I quickly stumbled on the solution: I relieved the headsail halyard tension slightly and it unrolled easily. I''m not sure if that''s your problem, but it is something easy to try.
