Hello, I've finally come on here to resolve my problem. People who say they have the problem, do not know how to solve it. Every time I click play on my private mod pack it just re-launches the launcher. My error is here.
If you would like to download, to see what is going wrong with my pack paste this: http://www.technicpack.net/api/modpack/mortus-ars into your mod pack.
or if you would just like the file download, here.
Thank you in advance to anyone who could help solve my problem. I bet it's something extremely stupid or small that I'm overlooking. I am not a coder so even the smallest help would be nice
