SWF and Player Controls in Quizmaker

Hi,

I am trying to import an SWF video file in quizmaker and I have done so before with no problem with other files. The video is less than 3 minutes long and I had it working before but now each time I upload the SWF file with player controls, the player controls move behind SWF and the SWF video moves to cover over other items on the screen. I tried making the video file half-quality, I tried creating a new quizmaker file with the swf file and nothing seems to work. Is there something else I should try? I am so confused because it worked before.

Thank you!

Kate
