I've been trying to join a couple private servers in the last days, and in all of them I have the same issue: After installing everything, when I start the client the button disappears and the window remains open, and the client does not start. I run a windows 10 64 bits system, and I have installed visual c++ 2010 both x64 and x86. Also disabled antivirus.
I have no idea what else to do.
