DW FTB modpack CC computer not starting

Heya,

I am building a huge frame quarry and want to control it with CC computers. But when I place one and access it, it doesn't give the text in the left corner, it is just pitch black. What is going on? Can someone help me?

You need to breack the wireless transmiter, place the computer, right clic on it and replace the transmiter. It might bug the server.
