I've added a button tot he info screen that will allow you to turn off SSL. This will allow the software to be used with the UCSM simulator available on the Cisco web site at http://developer.cisco.com/web/unifiedcomputing. This option needs to be turned off each time you run the application. There are some known issues with the simulator that can be found in the forums. There may be more problems, but it's a sim, so you can't really break anything. :)
Unless you want to run unsecured XML over HTTP, there is no reason to upgrade to this version.
