Hello,
Is your problem with the Web UI or with HDS/MSS? To use HDS and MSS you will need to use the createHDSStream and createMSSStream API commands, just as you do for HLS. You will need to set the targetFolder parameter to your web root (just as with HLS). You should then point your players at the respective manifest files:
HDS: http://IPofEMS/hds/manifest.f4m
MSS: http://IPofEMS/mss/manifest
To use the WEb UI, you will need to ensure that the EMS is running as well as your web server (Apache if you used the EMS installer).
Are you able to view your source streams with other protocols (RTMP, RTSP, etc)? Are there HDS/MSS files being written into your web root by the EMS?
