MovieLoadClip doesn't work with big files?

I have a huge SWF file (9mb) that I lost the FLA to. I would like to have it viewable online (even thought the preload will take a while I know…), but everytime I try to use MovieLoadClip to do this it doesn’t work. It works fine for JPGs and smaller SWFs. Is there a limit to the size it can preload online?

If so what are my other options?
