API wimtvpro error:

I am trying to set up streaming on my site. I fill in all the information that is asked for. As for the URL I click the link in this text (URL through which the streaming can be done. CREATE YOUR URL )and copy this {"streamBaseUrl":"rtmp://www.wim.tv:9090/live","result":"SUCCESS","buttons":{"btnGetLiveUrl":"Request us a URL for live streaming","btnEdit":"Edit","btnHide":"Hide Example","btnShow":"Show Example"},"liveUrl":"rtmp://www.wim.tv:9090/live/fcd016","streamName":"fcd016"} link information it gives me. When I click save I get the API wimtvpro error: at the top of the page.
