Hello, I am having the same problem. I have visited Themeforest to re-download the theme as you suggested above, but I cannot find an update. The version history document does not contain any release notes for an update. I have looked through the files and folders inside the ZIP file and they are the original ones, there are no updates.
I would really like to fix this as soon as possible since the accordion images are not loading at all in IE9. Do you have any instructions on exactly which files need to be modified?
