need mgcamd for vuuno4k blackhole

Hello
A friend of mine purchased a VU Uno 4k and installed Black hole 3.0.3 .
He also installed exactly the same mgcamd 1.38c like me and trying to work with the same server but it is not working for him
The only difference between us is the receiver model. Mine is Solo 2
Someone has an idea maybe ?
Many Thanks
