When placing Thistle into the Kettle the server crashes. Cleared out the configs on the server and the client and it still crashes.

Fixed it ... it was due to the config files ... again.

Resolved the crashing when the configs are bad by putting in a try/catch and added some logging telling users what to do when it happens.
