Everything was working but suddenly Wowza Streaming Engine stopped and it does not start anymore. I tried start it using services.msc as a admin but it was useless too.
Wowza Streaming Engine Manager is working.
Wowza version: 4.1.0 Windows 8
Nice hint ikikenis.
I saw the logs and it showed that my free license key was expired. I got another one and put it on the %WMS_HOME%/conf/Server.license.
Everything is working fine now. Thanks
