Spring RTS Engine

I'm new to Spring, but I've been having launching problems. Every time I try to start a game, it crashes, tells me a stacktrace is written, and terminates the program. It's happened with two mods and three maps. I don't know how to troubleshoot it so any help would be wonderful. It always happens during the "generating 3D trees". Thank you very much.

Go your spring directory, normally C > program files > Spring

Open up your infolog.txt and paste the contents of it to :
http://pastebin.com/

Then paste the pastebin link in this thread. The contents of the file will help us deduce the problem.
