Hull not found

Hi i bought the game 5 min. ago in Humble Bundle.
As I prepared to play, I found this error: Ship Hull not found -> Swarm Hathor Frigate:…\src\SIM_ShipHull.cpp 503
I have reinstalled the game but it continues to fail.

What can I do?

reinstall the swarm DLC . .
(GSB it trying to find one of the swarm frigates)

I´dont got the DLC

Ok, well that eliminates one posibility

Just checking something - have you (or anyone else for that matter) used any previous versions of GSB on the computer before ?
