Newbie with 3x E dongles on v7.4.4.0

[JohnRo79]

hi guys

i'm trying to start my first project and i'm stuck.
i've used the website and upgraded my dongles to their latest ezsp version (7.3.1.0)
and when i've checked the logs it was saying that "ember" is my best bet.

I downloaded the latest 7.4.4.0 and used the same site; everything went smoothly,
but now I'm encountering errors, and Zigbee2MQTT won't start anymore.

what am i doing wrong here?

also: please please please point me to the latest router firmware for my 2nd and 3rd dongles (both ember and ezsp)
