Honestly you're fine. At 40hrs primary ferm is probably halway over. Dont rely on the airlock. Take a gravity measurement. If its very close to OG then maybe you can repitch. I doubt that's going to be the case. Even a less than perfect smack pack will do ya fine. If there is less viable yeast, they may get stressed during primary fermentation and release more funky esters. In thia beers case, its not a Bad thing.
