Heya guys I am new blah blah blah. I need help, yesterday, my brother and I tried to start a server using "Host a Server" (rather than using a Dedicated one) but neither of us could see other (we tried Internet). We do know however that it is neither versions or serial numbers (we have one copy) because we are able to join the same servers online at the same time. So does any one have any idea or suggestions? They would be greatly appreciated.
