First of all I would like to say thank you very much for the great support. I asked a question, was getting a very fast and informational response. After this we had the problem with the function ini_set()(not enabled on our shared server) I have to clarify first with my provider.
I give 4 stars for the application and all stars for the whole service.
I'll pay for it even I can't use it actually. But this is it worth.
Thank you very much.
