I too am trying to get this to work with XP11.  I just can't get it to connect to X-plane using XPUIPC.  I have it working fine in XP10.  I downloaded the 2.0.0.0 version and tried it and nothing.  Then found a 2.0.4.7 version but that made no difference. 

I use Fs Commander and also use a Kacars program too that works in XP10 but these also don't work with XP11.  They all use XPUIPC to work.  So I'm interested in why some of you seem to have it working in XP11.  I'm using the very latest update for XP11 as well! 

Any ideas?
