Hello,

I have bought the upgrade version fo JoomSEF 4, but now I dont use version 3 anymore, so I want to buy the full version of 4.
Can I upgrade from the upgrade version to the full version?

Hello,

I don't think that's necessary. When you purchased JoomSEF 4 Upgrade, you gained access to the same JoomSEF 4 package as with the full JoomSEF 4 purchase. JoomSEF 4 Upgrade is discounted only because you used JoomSEF 3 before, there's no difference in available features.

Ok, but the ID is not working anymore, as v3 subscription has expired.

You should have received a new Download ID for JoomSEF 4 with your JoomSEF 4 Upgrade purchase, the one starting with 68d1... That one should expire on 28th January 2013.
