Hello,

I used the free version 3.4.3. Now I have buyed the pay version but I don't understand how it is possible to make the upgrade.

Hello,
please, read:
How to migrate free to paid version without loosing existing URLs

I solved the problem entering the id of pay version in the configuration, but:

- The link Joomla SEF URLs by Artio is showed in every page. I tried to make the manual upgrade with the entire package but without success. Have I to uninstall and install it? In this situation what files have I to save and reinstall (configuration...)?
- I have the paid version 2.06 of extention for virtuemart but it's not possible to upgrade it (not valid ID)

Thank you

Did you follow the procedure described in FAQ?

Yes Jan, I did it. At this point I'd prefer to uninstall it and reinstall it (I think there are some problems for permissions on a lot of files). But I don't know what are the files wich I have to save for the URLs already created.

Thats also my point tell me the simple way to convert the freeware into a registered one.
