3.0 versions do not work

[dejan]

Hi i am trying all the 3.0 Beta versions but they all have the same beahviour. I am using Windows 64x version with a Nikon D3300 camera connected wifi using the WU-1a.
The last application I have installed is the 3.0 Beta 9. It starts normally and i am able to change the settings, IC, MOCO, Rule 600 and DOF Calc but when I try to connect to the camera it simply doesn't do anything.
Before the 3.0 versions I was using the 2.9 and this one is working ok. I am able to connect to the camera and work with LRT.
I guess something big has changed between the 2.9 and the 3.0

I made a lot of changes between 0.2.9 and 0.3 but the connection functions are the same.
What type of connection do you use?
