Error in starting RRDI server

Hi,  We have configured RRDI with CLM 3.0.1.2 server. So for working smoothly.

Now RRDI services are down. When I try to start RRDI services, below is the error I am getting.

Request you all to provide your inputs/ solution.

C:\RRDI_INSTDIR\AppServer\bin>.\startServer.bat RationalReportServer -profileNam
