Maybe you are using the windows plugin streamer.dll for you're "server.exe" ?
And your host could be linux? if so you need to use streamer.so on your host (if its a linux server).
And add streamer.so to the plugins line in server.cfg. (also if youre server is linux).

Hope this helps i use this plugin/streamer and from my personal experience its the best i had problems once and it was my fault.

Also make sure youre using the latest include as well as plugin.

hope this helps if not try post Here
