Oh, OK. Thanks.

My order number is 14673, for "ninjamoons.com". My license expires on 1-Jan-2012.

I recently upgraded my website. Upon the purchase of the JoomSEF 3, I was running a version of Joomla 1.5. After the upgrade, I am now running Joomla 1.7.0.

I downloaded the JoomSEF 4.1, and installed it successfully.

However, when I go to "Components -> ARTIO JoomSEF -> Upgrade", I see the error message, "COM_SEF_DOWLOAD_ID_INVALID You will obtain the non-paid version of JoomSEF when launching upgrade from ARTIO Server."

Do I need to purchase another license to use JoomSEF 4.1? Or, can I use my existing JoomSEF 3 license?

On 1-Jan-2011, I had installed JoomSEF on two different websites, and it worked 100% with no problem.

But, on 13-Jan-2011, I installed JoomSEF on a third website. It does successfully transform the normal links to SEF links. However, when I click on the SEF link, I get a page which says "404 Not Found".

I have looked at all of the settings on this failing website, and compared it to the previous two, and it is absolutely identical. So, I am confused what I am doing wrong.

It is a very simple 4-page website:
