Umvbrella and Real Debrid failing to play streams

Hi All, im faily new to Kodi and real debrid but i managed to get it working great untill 2 nights ago, almost every TV show i try to play will start playing then after about 5 seconds bug message on screen saying it has failed to play. The file is still playing in the background but cant see it because of the message. If i download the same file it downloads fine and plays fine. im on windows 10 with kodi Nexus, everything is upto date and real debrid is paid up for 6 months, it also works perfectly on stremio with the same accounts. could this be something i have done wrong? thanks in advance
