I am just a mom who installed MC for my 9 yr old. I have no idea how anything works. I installed MC via the IE and downloaded the Traincraft MOD installer as this is what my son wants to install. I have done the you tube videos, followed the instructions and still have nothing. I have forge or I think I do, it shows up in my downloads. I recently installed Curse Client V5 and this actually got me further into downloading TC but it failed. After opening up MC through Curse, I clicked on the Traincraft MOD Installer icon on my desktop, it opened and I clicked on the Traincraft installer, it started to download but it first ask to back up MC which I said yes, well it then started but I got a error saying DAYZ cannot respond or something like that. I then did it again and said no to back up so it started downloading for about 3 minutes then I get the message: Value cannot be null. Parameter name: Path. That is it. Please help me. I have been trying to do this for over 2 weeks now.
