After License expiry Service Desk Plus is not starting

After License expiry Service Desk Plus is not starting

I have installed the SDP 7.0 trial version and license expired on 2nd October. I requested for extension of license to evaluate and present the SDP to our management. I got xml file containing licenses information by email. But the problem is that I can not launch service desk application to apply new license as application is not starting. Is there any other way of applying license such as through command line.
