If the crash report is in a text file, you should be able to right click -> coy and right click -> paste. Also, it seems like the text is not being copied to your clipboard. Can you paste the crashlog in another program like Notepad?
If it's a jar mod, then it has to go directly into modpack.jar on your client. On the server, I *think* it goes in the server's jarfile too but don't quote me on that
Most likely you forgot your password or the mojang login servers are down. Check here or here to see the status of the minecraft servers. If they are not down and you STILL can't log into your account, then reset your password
Correct me if I'm wrong but if the computers aren't connected to the internet, the only servers you can play on are locally hosted ones. If your internet is going to be cut off to external IP's like Google but you can connect to internal ips then you can still play on a server hosted on the netwowk
So recently I was trying to create a new pack for me and my friends to use. However, I have no idea how to install forge in it. Can someone point me to a tutorial or just explain how to get it working? Thanks in advance
