Buda, if for any reason you can not get biezom's method above to work for you then you could try using rtmpdump v 2.4 (I see you have v2.5) you can get it from:

Delete (or move) v2.5 from the RTMPDumpHelper folder and replace it with 2.4 - That's the only other thing I can think of. I tried using Google Chrome browser but RTMPDumpHelper failed to attach to the browser.
