I would recommend upgrading to the latest 0.8 release there are a lot bug fixes. (if not 1.0.10)

Have you been working at CL QUOURM and running repair regularly?
 
Am assuming the crashed server is totally dead and cannot be started. 

You can start a new node with the same token as the last one. When it joins the it will auto bootstrap and copy the data from the one that is up.  

If you can copy the data of the old one, copy it all to a new node and start with. Then run nodetool repair.

Cheers
