Hello guys. I usually never post here lol but something outrageous just happened to me. I made a piano arrangement of Avengers Infinity war trailer at 2 years ago. It was great! I got about 70000 view and 500 likes. But today morning. I recieved a email from musescore that they took down my score because it was copyrighted. I simply cannot understand. I posted the music as a arrangement. Not a original. And I also stated who made the original music in the first place. I cannot accept this.
Can anybody help me out? If you know how to deal with this, please reply. Thank you for your time
