Nothing of note. LFS CFG is fine, I've quadruple checked it. Insim port is 29999 (set ingame) and outgauge is mode 2/delay 1/127.0.0.1/ID 0(or 1, whichever the normal figure is, I'm on my phone and can't remember which), port 30000. Outsim is 0/0.0.0.0/0/0 etc, no admin password either.
No other programs are run with LFS. I installed LFSLazy today but the issue predates that.
