top was working fine then tried to put it up but wouldn't work. on 1996 Audi Cabriolet

the back part started to unhinge but then it stopped. Only went so far . Acts as if the trunk weren't locked but it was. This is safety feature i guess that trunk is locked and if it wasn't the back part of ytunk mechanism only opens so far then stops. That is what this just did but yet my trunk is locked. Please help ASAP....of course there is rain in the forcast!!!
