Thank you very much for your confidence in my extensions.
Your Joomla version is really really odd! I can send you an old version of Securitycheck Pro, but I don't know if I have backups for your version. Take note that Securitycheck Pro is a Web Application Firewall, so it can't protect you against certain attacks if you have a Joomla vulnerable version as you have. Also that old version doesn't have all the improvements added during updates.
