I have a defect in the carrier scenery. The carrier is fixed upon an island. May be someone had the same problem and fixed it .
In this case please give me some advice. Thank you.

Dear Firebird,
you have found the solution . The reason was a corrupted bgl file . All scenery shows up now without an issue. Thank you so much.

After installation of the scenery EGUL V2 appeared a big square on the ground texture in the colour of red and black. I suppose nearby city of Corby.
I tried various times to install and uninstall but the issue is allways the same when EGUL is activated.
I have default FSX scenery for Great Britain ...
