LiveOSC not working on Windows Live 10.1.42

[whiskyplausible]

I've installed the LiveOSC fork into two different installlations of Live on different computers. Neither worked, and the sockets were never opened.

Output from LogServer.py was pretty consistent:

I tried tinkering about with the code, but didn't make it very far due to the sockets being wrapped etc, I tried settings ports other than 9000/9001 and this also didn't work. Since it didn't work on two different computers I'm thinking it wasn't the vagaries of the networking setup on one of them that was causing it to fail.

I didn't quite understand why it starts up twice - I tried to prevent it doing this using a locking file, but it still didn't work (just didn't show any error messages). I'm going to see if I can try it in a copy of Live 10.0.0 next.

Edit: same problem with 10.0
