What exactly is the version number you have?
Sorry, the newest version just doesn't say much.
The latest version available is 1.2 RC2 (as stated in the extension description above).
This 1.2 RC2 version is Joomla 1.5 native (no need for legacy enabled).
No complaints here, but one thing I would like to see in future releases is a radius search function.
Bottom line: This plugin/component is worth more than it costs.
