Replying to Flash in Premiere?

I'm slowly learning After Effects, but need a quick animation for a video I'm working on right now. I'm decent at Flash animations and I've used them before in Premiere (back when Flash was under Macromedia), but can't seem to get them to work properly in Premiere CS3. I know this isn't a very standard procedure, but I was just wondering if anyone had ever messed with this. Oh, I'm editing 1080p footage, if that makes a difference (I'm sure it does). Thanks!
