After loading, lightroom crashes and shuts down. An error message comes up which I have sent of adobe. I use Lightroom CC. Any help would be appreciated.

After loading, lightroom crashes and shuts down almost straight away. I have tried numerous times over numerous days however it just keeps happening.   A couple of times it showed an error message which I sent to adobe but no answer from them.  I use Lightroom CC.  Any help would be appreciated.
