Hamachi: Yellow Triangle

How can i fix this: 

I downloaded hamachi, then I opened it and I joined to my friend network. Then there was yellow triangles next to each username. I went to device management and there was also yellow triangle next to "Hamachi Network Interface". On hamachi I can talk with peoples but example when I try to join minecraft server with hamachi, it wont work. 

Would be nice if somebody help me to get Hamachi back to work. 

Thanks already guys!
