Well Client and the Server are actually Different, but there are Many Tutorials that can Help you out... And if you want help too i could help too (btw ... I got my Server running but cant Enter with an Gpotato Client the Server lolz)
Tbh I would worship some help. Me and my friends are devastated.I think i'll clear everything and start over. Do you know where i can at least get some clean Server files? The one i have from Kevin is not working out for me at all. Also i am using Hamachi
I also Have Kevins Files.. and they work out for me after i found out some stuff that was pretty stupid.
If you want to test That your Client Works ... I also have Hamachi so you can test out My Setted up Server Files if they work... Well who knows... maybe they work or not.
