Hey, i am trying speedrunning for the first time on a competetive note.

My issue is, i dont know if custom (non copyright music) is allowed in a recording and if yes or no, how does one submit a run? upload it into YT?

I am basicly just now getting actually into speedrunning (Need For Speed Carbon in particular), but my LiveSplit wont work when i press the buttons. People on then internet said that running it in admin mode works....it does NOT for me....i also run games as well as livesplit as admin AND i got Global Hotkeys enabled...but still, no matter what button i press or assign it wont work
