Don't worry, WM Recorder is a great stream recorder. And if it doesn't work for you, you still have a 30 Day unconditional money back guarantee!

"Invalid URL or No URL provided" message usually appears in the URL mode. This mode of WM Recorder is used only if you know the exact URL of the stream. In most cases I get this message in the URL mode when I haven't entered the filename. I wish the filename can be generated automatically in the URL mode, but it is not...

But there are two other modes of WM Recorder: ADA and PRO. ADA should be used by default. I also suggest you to use "Auto recording" with ADA or PRO, because this allows to record audio/video streams automatically (All you need to do is to play an audio/video stream you wanna record).

So switch to ADA Auto recording mode and try to capture your stream again.

Please note that some audio/video streams can't be recorded. You can post the URL here so that we can test it to make sure that WM Recorder or any other streaming media recorder can handle the stream.
