I'm sorry to hear that. I don't know anything about Linux; I just use the export feature Ren'py provides. I'll try re-exporting it tomorrow or the next day and upload that. In the meantime, I'll remove the broken Linux version from the page.
You know, actually, maybe I'll try the joint Windows/Linux build instead of the separate ones. I've been using the separate one to make the downloads smaller, but maybe it's more reliable to do the joint one and that's why it's the default setting.
