Prolight laserharp controller

Hi guys. I´m new in this forum but thought i´d try to see if anyone could help me. Anyone had any experience with laser harps? I recently bought a laser harp controller from Prolight here http://www.laser-harp.com. Later on I bought a cheap laser projector from Casa http://www.aliexpress.com/item/singl...728697488.html.

I couldnt get the two to work together, and in the beginning I thought the problem was in the controller. I returned it to Croatia but they couldn´t find anything wrong with it. The problem must be in the projector itself. The guys from Prolight suggested that it may be because of too low frequency in the laser that causes small disturbances in the beams so that the censor can´t detect them at all. Does anyone have any laser projectors to recommend (ILDA) or websites that sell them, preferrebly that they know works with the laser harp controller from Prolight? I´m looking for one as cheap as possible as I´ve arelady spent a lot of money on bad laser and shipping. Hope someone can help me. Not alot of laserharp-knowledge in Norway;)

Thanks!
Magnus
