Hi Umberto,
I posted this in another post but have a feeling it got lost in other discussion so apols for starting another post.
I've installed most the FSdreamteam sceneries without problems but about a month ago I downloaded the KORD update and ran into problems. My antivirus was NOD32 v4 and not had any problems up to that point. I have always had couatl.exe and bglmanx.dll added to the exclusions (as well as my FSX folder). When downloaded new scenery I've always turned off the real time scanning aspect while downloading from the website and while installing (and right click to run as admin).
Since installing the KORD update I've not been able to get couatl menu in FSX (I've the add on manager menu). I realise it's not the install per se but something blocking couatl but running out of ideas.
Initially I presumed a bad install so I uninstalled and also removed addon managed and couatl when asked and then reinstalled with the antivirus turned off including realtime scanning but no success. I then uninstalled an previous airport (KLAX) that was working fine and reinstalled as above to no success.
Convinced it must be an antivirus problem I actually uninstalled my antivirus completely (I was due to upgrade to v5 anyway), rebooted, uninstalled a scenery and addon manager and couatl, mande a fresh download with no antivirus (not too concered as usually turn off anyway) and installed without an antivirus on my computer. I did have windows defender installed but believe it's not caused problems before.
I've still had no success to get couatl running and not sure where to turn next. I've only used the ESET products for about 3-4 years with no problem, but even with no antivirus installed am still getting problems. I use Windows 7 64bit and the only firewall is the default windows 7 one.
My computer specs are

Have attached my FSX.cfg file in case thats any help. Since the original post I've again tried with all the real time scanning turned off when downloaded and installed and readded the exclusions for BGLMANX.dll and Couatl.exe but again no success.
Thanks for your help.
