POSKY autobrake on the 737

Hello,I am having the following problem in FS9 with the POSKY autobrake on the 737s: it won't brake.Let me explain the issue. I first installed the autobrake gauge on the default 737-400 panel, went for a spin and when landing, spoilers go up (as they should, controlled by the gauge) but no braking... Then I tried an RTO with the same results, spoilers will go up but no braking.I finally aliased the panel to the POSKY 777 panel (where it works as it should, brakes and spoilers) to no avail... I still get the spoilers up automatically but no braking.The aircraft and gauge were dowloaded from the POSKY site and i'm using FS9.1Has anyone had the same problem?Regards,cmercier @ MMMX
