SCOM 2012 System Center Operations Manager has stopped working when adding Web Console.

I am trying to ad the Web console to one of my Management Servers but at the point where it asks what website to use it fails with the "System Center Operations Manager Setup has Stopped working error.

This is the included information.

The only error I get in the log file is this.

Error::Error:IsReportingValidToInstall failed SRS instance not provided 

I don't understand why I would be getting an SRS error, our reports run fine.

Thanks,
