Hi there. Need someone's help with this one, as I've searched the forum, but this specific problem doesn't come up.I've done Tutorial 1, and I'm now on Tutorial 2 (Advanced). My system and addon specs are in my sig. I've positioned the different files as instructed, and I don't have FSDT airports. My addons are also on my sig (GEX, UTX, etc.)Here's my problem: when I reach the FMC section where I need to enter the SID and runway for KORD, I hit a snag. When I press the LSK to select KORD to take me to the LAT REV page, I get a "Not allowed". It won't let me get to the LAT REV page. I have restarted the saved flight many times, using different scenarios (straight from the loading page of FSX, and starting a default plane, and then loading it.) I also load the panel state for the flight after loading the flight.I've also gone back to Tutorial 1 to see if I missed any steps, but I haven't. IRS are aligning correctly, fuel is pumping, but FMC just won't allow me to go into KORD LAT REV page to select the SID and RWY. Please help, as I'm stuck.Thanks,David Bolanos

Make sure your navdata and sidstar data is same cycle. KORD has a new runway and old runways renumbers, which will cause sidstar errors. There are no sidstar error messages in the MD-11, it just gives you a blank page.

Thanks Dan. I just installed the latest Airac from Navigraph, and I still get the same error. Here's one I don't understand: after clicking several times the LSK with the Captain's side FMC, I tried the FOs FMC, and it works each and every time! When I click the LSK of KORD, it takes me correctly to the LAT REV page. If I use the Captain's FMC, it will not work (I get "Not allowed"), at least for this flight. Tutorial 1 gave me no problems, however.I also tried creating a flight using FSBuild, same airports KORD to KJFK, all with very similar variables as the advanced tutorial. Initially, I had the same problem with the FMC ("not allowed"), but after clicking the LSK 2 or 3 times using the Captain's FMC, it finally went through to the LAT REV page. I have no idea what's going on or what may be causing this, since it works with the FOs FMC. I'll keep testing other flights, but at least I have a way around it. It doesn't seem like anyone else has encountered this issue.Thanks,David

I seem to have found out what was causing the problem - I tried another flight, from KMIA to KATL, and had the same issue with the captain's FMC. Even though nothing was showing on the scratchpad, I pressed CLR several times out of frustration, and this "cleared" whatever was stopping me from allowing it to move onto the LAT REV page. I then tried the advanced Tutorial, and when I reached the FMC KORD (LSK) to go to LAT REV, I pressed the CLR button a couple of times, and then it works - using the captain's FMC.There is nothing visible on the scratchpad, as I said, but perhaps there is a "ghost" writing there - pressing CLR eliminates whatever is there, and solves it.Thanks for your help,David
