Now i realized why there is no demo of the solution. If there could be one, a lot of customers would not buy it.
I opened a ticket 12 days before for a CSV adress book import issues i am facing and is still not resolved.
12 days for a ticket of mapping one simple CSV file. This is a task of few hour of programming.
I regret for buying this product a year ago. And now they want to take more money for the "upgrade protection".
If there was a demo i could think twice to buy or not the product.
