My launcher can't seem to launch monster, I think this is the problem:
[INFO] [STDERR] Warning: version of ForgeMultipart-universal-1.6.4-, 126.96.36.199 is newer than request 188.8.131.52
Here's the full report: http://pastebin.com/ZjdBHtE6
i have 16 Gb of ram, so if something is limiting that it should be an easy fix.
Ok there is also this:
