Problems with kantan mapper 088

Hi everyone.
I had some problems and bugs with Kantan Mapper which i will be grqtefull if you help solving that:
1- My PC supports 4 display outputs. But when I connected 3 projectors and 1 monitor to it,I lost the displays simantanously several times and couldn’t work with TD. The cable was too long, could it because of that ? If not, so why?

2- the second problem which annoys me is that when I click on the “Enable output” in the Kantan mapper control panel, I loose the software control (the main page is gone) and can’t do anything until i disable output. What would cause it and what is solution?

3- I set the sound output but it didn’t work properly and just background music was played and we couldn’t hear thenarrotor !! However with other players I didn’t hame the problem! What it cause and solution?
Thanks
