Trying to download using rtmpexplore

hello,
i tried to download HD videos of a website, i tried rtmpexplorer and it worked but today it stopped and tried to resume but nothing happens and gave me some error alert in the command line window , i tried to copy the command generated by rtmpsrv.exe but i can't i wonder if their is a way to do this so i can show you exactly what happened , by the way I'm using avira internet security and its in the "allowed" list .
i noticed that the when rtmpsrv.exe picks the link from gui "rtmpexplorer " and generates the right command it didn't add "-e" to the code so it resumes .
i tried using rtmpdump only but its hard specially with some websites it never works .
