First question...

What exactly is the the difference between the version of 3.0.1 that you download without support/extensions and the version that comes with paid support (if any)

I've installed 3.0.1 on Joomla 1.5.0 in legacy mode. Installed the .htaccess file, though it seems incomplete compared to earlier versions...

added the patch to router.php, set the config options (even copied them directly from a site that I KNOW is/has been working)

And, nothing. The lame-o default Joomla SEF kicks in, Artio doesn't take at all. Am I missing something? Nada with metabot, nada with anything - uninstalled/reinstalled about 5 times, redownloaded a different copy.

How tested is this version? Would I be better off waiting for an update?

Cheers
