Are you certain you fully uninstalled the original files you had (fully delete them - everything. Not a trace behind)?
Make sure you've done that and then download the 1.1 version on the game page. It looks like you're still using older files.
I've scanned the code for this sprite conflict , and it doesn't appear in the latest version of the game I have at present. If it persists after deleting everything and starting from scratch with the new files, let me know.
