Commedia for Joomla 1.5 and Commedia for Joomla 1.6+ are two different projects. Those are different programms. It's not one component.
Commedia for Joomla 1.5 can not working in Joomla 1.6-2.5.
Commedia for Joomla 1.6+ can not working in Joomla 1.5.
Those are two different extensions with similar functionality.
Why is it not fair? When You bought Commedia i asked You wich version of Joomla do You have and for wich version of Joomla do You need Commedia. Also i add information
here about price of every version and both of them many time ago. So i add that informtion earlie than You bought Commedia.
In other Companies there are other rules, some give You extension only once and You must bought new version again, another give the link for year or half of Year. Is it not fair? They do not lie to You cause they give that information to You, so You can choose that extension could You buy, or another.
So am i. Sorry. Hope, You'll understand me.
