Playing video clips twice in a row

I changed my experiment so that in a certain block (Beat), a video plays twice, with an ISI of 2000 ms. between plays. The second time, the video plays as it should, but the first time, I hear only the soundtrack, with a blank screen. Can anyone tell me why this is happening, and what I can do to ensure that ss see the video the first time, as well as the second?

I am having trouble uploading the entire .zip file, so I am attaching the .sl4 file. The movies are .wmv files. I am attaching one of these as a .zip. Please let me know if anything else is needed.

I still think a great deal of the files are missing. I will contact you via private message.
