I fixed it now, but I am completely done with Skydaz.
Haha I was getting the same crash report when I downloaded Forestry from the official website, so I tried Skydaz but I was still getting the crash report and that is when I hoped onto the forums to get some help. I updated my Forestry now though and my pack is coming along great!
