Replying to Help uploading my 1st edit

so im new to the whole editing and dealing with computer bs and i cant seem to upload a little cliffjumping edit i made. Its saved to my computer in videos as a widows movie maker project. on youtube it said error, on vimeo its not big enough of a file, on facebook it says its not in the right format and on here it says succes but never comes up. how should i go about uploading this (preferably on here)? this is annoying as shit
