Originally, Apsona was conceived as a money making idea. I cautioned them early that I didn't think it would be that. They decided to release it for free. Why do you expect technical support from a free - now open source - script? All the answers are here in the forum just like every other mod. Torvista just posted the fixes needed for 1.5.3 functions that require the mysqli. It all still works in my client's 1.5.1 carts.

How about posting your problem (after seeing if you can find an answer first if possible as you would for any forum thread)?
