Audi TT Roadster roof lock handle stuck
 

I have a 2003 Audi TT Roadster. Today when I put the top up, I twisted the closing latch a bit too far, and it stuck. It’s rotated about 20 degrees further than the normal locking position, and it won’t budge. Anyone experience this before, or have an idea how to unjam it? Thanks for any help.
