I'm a bit stuck then reallyFor now you could make a new blog post and link to the one on Newgrounds (Click on your username in the top-right, go to Blog, and press New Post).
While you made the file in a different program to Adobe's one, if it is a real swf file then it should have the correct MIME type for it too. Maybe other websites don't check it for that reason, I really don't know
The whole place needs re-coding if I'm honest, and I'm planning on doing that soon so don't worry.
Really sorry that I don't know what's going on
Sorry to disappoint you
Don't worry about it. The cartoons I was going to submit weren't that good anyway.
