I integrated the fixes to get the YouTube and Vimeo addon working in Gotham Beta 2. I uploaded the addons with the fixes. Just uninstall your current addons and manually re-install with the fixed addons. For the YouTube addon, it’s advised to delete the cookie “yt-cookiejar.txt” located in the following folder: xbmc/userdata/addon_data/plugin.video.youtube. For windows user’s, you’ll find the xbmc folder in C:\Users\UserAccount\AppData\Roaming.DOWNLOAD LINK: https://www.mediafire.com/folder/ie3ammajgrc2o/xbmc_addonsLIST OF FIXES APPLIEDYOUTUBE FIXESTo solve the login problems, I added the fix from this post: Reply #52.
