Hi Raul,
I can't reproduce on my end, though. Can you try the standard troubleshooting steps to see what may be interfering with the Carousel js? Try deactivating your other plugins temporarily, then reactivating one by one. ALso, try switching your theme to the default TwentyTwelve temporarily to see if it's not an issue with someonething being lodaed by your theme.
Let me know what you turn up!
