Reactivation not work

Hi Massimo,
the reactivation is only needed in order to be sure that the system is connected to the internet to check for security updates and help us, as marketing review, to understand how many people is using it in the world.
May be the problem is that you have removed manually some tables from database while the reactivation is done usually by the web interface.
In case you have wrong remove something you can consider to make a backup and after try to update to recent version and activate from it.
I guarantee that we support also the reactivation of old versions. This suggestion is in order to fix the problems that can be made from your hack.
We don't want to suggest you how to work with your customers, but we think that if you want to give professional services with an open source solution you must be able to do it by yourself otherwise is better to buy some support from vendors or other professionals that well know the product you are using to make money.
best regards
