That's the same problem i've had with them, they just send me an obscure question about it. I end up sending them in writing that it's my own origional animation and that i made it in flash cs6 and forward them the eula. Usually after that they accept it. However with my latest vid i got with a notice again and this time on the page where it asks where you got the visuals there's a new box where you can say "i made visuals in software x, visuals are third party or visuals are public domain". Entered that i made them in flash cs6 so we'll see what happens. If it gets denied i'm going to be insanely mad since it's all drawn from my own mind/sketches.How does one prove you made it? Do they ask for the original files or something?
