My first flight (BFI-DEN) was perfect. Second flight is DEN-SLC, or at least I'd like it to be. Here's my problem. I am using the same plane (Delta with WLs) for the flight. Everything is set up properly (I'm pretty sure). FMC is set up, Runway 25, ROCKI7 EKR LEAHY3 BOAGY.ILS34R. I line up and press TO/GA, everything works properly. At EXACTLY 60kts, two things happen:

• The sim stops accepting inputs from my rudder, throttles, yoke.
• The DUs freeze.

I cannot check for failures because the Aircraft page of the settings is blank. I have tested this about 35 times now with different variations trying to get it to work. What I have tried:

• Different SID combination
• A completely new flight with the same set up
• Different 737-800 (PMDG House)
• Restarting FS
• Departing different runway
• Completely removing the Delta livery using the livery manager, then re-installing the current livery
• Departing a different airport
• Not using TO/GA

What worked:

• Creating a new flight, with the same aircraft, but NOT setting up the FMC. All I did was start the engines, set the flaps and took off with manual throttle control.
• Using the same Saved flight that wasn't working, I cleared the route from the FMC

Testing the Route:Since it's apparent something in the FMC is causing this error, I was able to go through my set-up and determine that the problem is being cause when I set the approach to the ILS 34R using the LEEHY arrival. If I change the STAR to the JAMMN, then the same runway (34R), it works fine. But that particular combination is causing the problem. Also, if I simply change the runway, the error remains. I have to clear the entire route, then rebuild it with a different combination for it to work properly. Anyhow, I've been at this for 3 hours and I'd like to do my flight (now that I know what's wrong). Hopefully this helps you guys out since it sounds a lot like the issue you guys have under investigation in the stickied post. Edit: same problem with the SPANE arrival/ BOAGY.34R combination

I ended up changing my arrival RW to 34L and there's no problem
