Hobie Getaway Sail Raising Problem

Almost from the first time we went sailing with our new (2002) Getaway, we have had problems getting the main to go all the way up. Almost every time we raise the main we have to tip the boat over and work the main sail past this point manually. We try to smooth out the part of the sail that rides in the groove as much as possible, but after trying to get it past this point it always ends up "bunched up".

Was the mast assembled incorrectly? It sort of looks like it is not quite lined up right. Or could this be some kind of design flaw? From reading the Hobie Cat forums it seems that several people are having this exact same problem.
