Problem with slideshare embed after the 'player' was updated.

We have a slideshare presentation embedded in a php page on our website. It was working fine till a day back. I think some changes have been made to the 'player' of the presentation, because of which it is not working properly today. We have reduced the size of the presentation (by editing the embed code) and now the bar which carries the next/previous buttons etc. is showing a white strip.

Any clue?
