Hi yesterday i've tryed to do a flight with this route : After i insert all the sid and star the sim freeze, if i try a different route or the tutorial this doesn't happen could you try to start a flight and configure the fmc to see if works with you The route is this one: Departure LIMC RWY 35l SID FARA7C.NED8U ROUTE : NEDED UM984 DIVKO UN852 VERSO UL129 LUNIK ARRIVAL STAR LUNI1PB Or anything with LUNI inside ILS 24R(Z) no transition Pass Load 100 % Fuel left 3650 KG right 3650 KG CArgo 1500 KG FW 1500 KG AFT FL350 CI 25 PLEASE ALSO BETATESTER TRY THIS ROUTE EXACTLY AS I INSERT AND YOU SEE AFTER STAR INSERT AND ARRIVAL RUNWAY 737-800 WL pmdg Livery crash I have tryed 25 times with and without meteo fresh install of fsx with uac off all settings raccomended tryied with 2d and 3d cockpit win7 64 With others route furtunatly works the airac is the original one with NGX Please i think is a bug with some parts of AIRAC try it

Hi, I see in the forum that many people are having fsx that freezes. I used to have that too but after I removed the Uiautomationcore.dll it didn't happen again. But that dll is needed in many other applications I think...

UL129seems not longer to be avaibable sorry, its still there - my fault

Yes but in the airac UL129 exist and the problem is only after i finish to insert the entire route with sid and stars aviable corretly in the airac 1108

What is the destination airport?

LEPA sorry

Please could someone try it i've gone to bed at 5 AM for this :(

Marco, I can't yet see why but your flightplan and loading does indeed lockup FSX.

thankyou for trying So is not mine problem could someone from PMDG try it ?

I just tried it with the -900WL and that didn't cause any problems. (I'll try again with the -800WL, which was what I meant to do anyway, but somehow I loaded the -900 instead).

It seems it something related to airac versions, double check them within your flight planner and/or if you have fiddled with them on other sections.

Sagga- What is this dll that you mention?

I have tried with pmdg 737 original airac and the navigraph one 1108 what're have tour used with 737 900 ?

I tried again with the -800WL, same result (i.e no problems). Maybe it has something to do with the eact sequence of the entries? Obviously there is some problem since Stephen was able to reproduce it ... This is with AIRAC 1108, the one that came with the 737. / Tom Scratch that, mine freezes too. It didn't happen on route entry / activation, but when I tried to fill in the PERF INIT page, FSX froze..

Robert,It is the DLL most users place in the fsx root dir to stop menu crashes (full screen mode) when using heavy payware aircraft. PMDG747 for example. CheersJulian
