How to Reinstall Crowd without access to the old CrowdHome

[Chris Hardie]

We had a hard drive failure and lost our Crowd installation and CrowdHome directory. We brought up a new server, installed Crowd, configured what I could,  and I cannot seem to get Crowd to work with the current database. I go through configuration and it connects to the database and errors with "The Database contains existing data". I cannot figure out where to go from here to get past this error. The only option I see is the checkbox for "Overwrite existing data" for a clean installation of Crowd which I do not what to do.

thanks
