I had been using RP successfully and then I began not to be able to download videos. I deleted the program and reinstalled. I can now sporadically download the featured video on YouTube, but if I search for and select a music video it will play both on Chrome and in RP while I get a downloader message saying unable to download (on RP itself) or no videos at the web (at RP downloader). How can I resolve this? RP was working 48 hours ago.
