unable to make EMS work

I still get the same error ” Could not connect to 51.15.128.57! Either EMS is stopped or the firewall settings (and/or SeLinux) of the target machine does not permit connection to port 7777. Kindly consult the user manual.” also if i look at the top left corner it says ” • EMS STOPPED • INSTALL EMS LICENSE” • • • • Also i got another question. What if we get a client with without a browser that supports flash? What would evostream do? Would it display nothing or will it display another format of the streaming?
