I'd try re-downloading the file. I know that it worked in 10.04 for a while for me, but then it stopped working one day (I probably broke it somehow).
I know that the linux version is quite out of date and they're hoping to have a new version soon, but there's no concrete date set as of yet.
Try re-downloading and see if it works, if not, you might have to pick something else for the time being.
