Subcon was having some problems using the newest psl1ght and toolchain (the one where the toolchain autoinstalls psl1ght). Look for an older copy of the toolchain (late dec to early jan-ish I think?) Or PM me if you want a copy of the source I'm using posted if need be. That would be my first guess as to whats wrong, Robo hasnt updated his psl1ght/toolchain to this newest one I guess. Sometimes Robo has been known to miss files during the push, so it could be a missing file. Hard to say and I would run a test compile to eliminate that factor, but I'm not with my psl1ght machine right now. If this isn't worked out and answered when I get to it, I will try.
