I am assuming you mean this http://www.aero.sors.fr/navaids3.html
 
World navaids updates FSX or P3D. Not related to the aircraft you fly.
 
For the likes of PMDG and others, they use AIRACS which can be purchased for a nominal fee from the likes of Navigraph or Aerosoft Navdata pro.

Navagraph offer a subscription service which includes maps.
 
Think you maybe mixing the two up. PMDG provide airac that was current at time of release.

Sounds like you do not have simconnect installed or incorrectly installed. I understand both the iFly and MJD8 both work.

Do you have insurance 1251452 ?
 
Seriously, can you post a screen shot of your problem. It would save a lot of guessing.
 
Unless you are a Secret Agent, (007) can you post your name ? The only people I call by number is my kids, as I forget there names.

Hi  Jamaljé,
From the Opus faq:
 
"
This is not an OpusFSX problem, we have just provided a solution to a problem that occasionally occurs on some systems due to a corrupt or faulty cirrus overcast bitmap mask file in the FSX/P3D Texture folder. If your system has a faulty bitmap file it will be quite obvious, there will be a thick cloud hovering above you wherever you fly. 
Betas 2.70.2 onwards automatically fix the problem on a restart of OpusFSX, but if you have an older version and your system suffers from this problem then please follow the instructions below for the cure.

Make sure you have disabled your 3rd party weather engines and in addition disabled/removed all their visibility, haze and fog effects. You must replace the cirrus_overcast03.bmp file within your flight simulator's Texture folder as follows,
1. Navigate to your simulator's texture folder, either <FSX>\Texture or <Prepar3D>\Texture
2. Rename your cirrus_overcast03.bmp file to cirrus_overcast03_foggy.bmp.
3. Truncate our cirrus_overcast03_Opus.bmp filename to cirrus_overcast03.bmp.
4. Restart your FSX or P3D simulator. "
 
If you need a replacment, PM me your e mail and I will send you a replacment Cirrus_Overcast03.bmp.
 
I realise you don't use Opus, but it helps explain your issue.

Gear not mapped to hardware. Have downloaded a new copy of ENGX, and testing now, first with the -800 then -700. So far 2 flights using the -800 have been trouble free. Fingers crossed.
