645D + Image Transmitter 2 = compatible?

I bought a 645D including Image Transmitter 2 last saturday. I really love the handling of the camera but have problems to set up a tethering connection, which is key for my workflow. This is my setup:
- Pentax 645D - newest Firmware V 1.33
- Macbook Pro OSX El Capitan 10.11.4 (newest Version)
- Image Transmitter 2 (V 2.1.0 (1) - newest Version

The USB-Connection of the Camera is set to PTP. Image Transmitter tells me "This camera not supported".
Is it possible, that I got the wrong software or is there perhaps something I´m doing wrong? I tried 3 usb-cables and 2 usb-ports. My Canons are tethering perfectly.

Many Thanks for your support,

Maybe the wrong Version. I've heard that the Image transmitter 2 ist for the 645z, maybe that you need an older Version (Image transmitter). Simply ask your vendor or pentax support directly

Many Thanks! I forgot to write that I already phoned my vendor and pentax support. In both cases I didn´t get the dedicated 645-specialists to the phone, but both very kind. The link to B&H helped a lot! Phoned a third time and get my IT 1 now. Hope, it solves the problem. Of course I will post the result here for others facing the same problem.

Version II does NOT work with 645D

PK-Tether (Windows) worked if you don't shoot to frequently.
The Downloadpage is down. Ask, if someone still has a copy.
