Transcoder

Guys  when  I'm uploading to youtube, i got two  videos on  my  Desktop  and my  PC is a  HP with Windows 8.1. alright let me get right to it. with windows Movie Maker 12 is out i was able to upoad straight to youtube from  movie maker. now  when i try  to  load a video file into it the Transcoder  stops. I do  have a  picture i took as well. but  Anyway  I'm usually   uploading to youtube from  movie maker but  when it  starts it  just  says Transcoder  has  stopped working and close it. along with the  video saying it  can not  be  loaded into it. I tried re-installing the   movie maker Windows Essentials 12 for it and repairing it and yet  same  stuff  comes  up.  I  tried going back to  an older  version  but it just  closes as soon i  put the file in. anyway  i was wondering if there was an  upgrade or  hopefully we could get an   updated version  soon  with all fixes and  more and hopefully  I  can get  help for this as well.
