vuplus solo blackhole

Hello everyone,
Im new on the community and have got a problem with vuplus solo blackhole.
Its running with LAN CABLE or WIFI and the setting works, the signal very good but infortunatly i dont get pictures(except few channels)
That vuplus solo box was configurated by a guy we knew and charging to much money everytime the box was crashing down because of bad weather he had to come to set it again and charge me money, the last time i spook to him , he told me that it needed a new server,
could please please someone explain to me the meaning, im very clueless about all this.
Tks a lot Mau
