I think I found the solution.
First open the .swf using winamp (or something similar)
Then try a lot of times. When the swf works on winamp. It will work on the flash projector.
I'm not sure how it works myself. I think winamp will become a catalyst for the flash projector to access the internet.
I was just doing something random and poof it works. Everytime the .swf becomes faulty again I'll do the same thing and it's fixed again.
I hope this helps ^^.
