Please note, that your free upgrades period for:

JoomSEF 3

I tried to upgrade the extensions and it says ,

Your upgrading license has expired. You can renew it by making a new order. You will obtain the non-paid version of JoomSEF when launching upgrade from ARTIO Server.


Also when i try to access the module it says,
